Paragon FireFly Kilns For Annealing, Beads, Ceramics, Dichroics, Enamelling, Fusing, Sagging, And Slumping Glass, Heat Treating, Melting, Moulding, Metal Clays, And Porcelain.

Paragon FireFly kilns are generally used for ceramics, porcelain, enamelling, glass fusing, glaze testing, annealing beads, china paints, decals, dichroics, heat treating, melting gold, moulding, and silver clays, although they have other applications.


There are two versions: the FireFly and the FireFly W. They're 1290°C cone 10, square, plug-in, top-opening, table-top kilns with firebrick interiors and Sentry Xpress 3-key programmers. The FireFly has a plain lid the FireFly W has a lid with a window, shown in the second photo above.

The FireFly and the larger Caldera look similar, but there's an important difference: the Caldera can accept clip-on collars between the base and the body. The Caldera X collar increases the internal height, the Caldera B collar increases the internal height and has a bead-annealing door, and the Caldera E collar increases the internal height and has an enamelling door. So it's a good idea to read about them before choosing?


Both versions are described in detail below so, although there's a comparative table and photos, I recommend that you set aside some time and read about them.


This internet resource is very comprehensive so is much easier to use on a computer than on a tablet or a phone. If you want to compare the different versions you could print the relevant pages. They should print correctly on A4 paper but check first in Print Preview so that nothing goes missing, particularly if you normally use wide margins. Fast or economy print will use less ink.


Yours can be in Paragon blue or customised berry, black, jade, navy, pink, purple, or turquoise: although customised kilns are made to order, so can't be returned if the colour isn't exactly as in the photo. And it's only the control boxes that are painted: not the whole kiln.


They have the popular Sentry Xpress 3-key programmer. Features include twenty-five free-to-set sequences, each one with up to twenty segments. The cone-fire mode, up to cone 10, will simplify your work with ceramics.

When the programmer turns the elements off at, for example, 700°C, residual heat will continue to increase the temperature briefly. A small kiln might overshoot to, for example, 715°C before dropping back down. The programmer's software slows down the heating just before the target temperature, reducing any overshoot and improving the accuracy.

Digital programmers allow you to set up sequences, each one with multiple heating, holding, or cooling segments: so you can choose the heating and cooling rates, target temperatures, and hold times, save the sequences, and re-use them.

Being able to create, edit, and save your own programmes is important because, having experimented and diversified, most people fire materials, or combinations of materials, at different temperatures and for different times than are recommended.


The firing chamber firebricks have notch-joints at the corners: much stronger than the butt-joints or mitre-joints generally used in small kilns.

The elements are in dropped recessed grooves in the 64mm thick firebricks. The kilns are fitted with a switch that cuts off power to the elements when the kiln is opened: a UK-EU legal safety requirement.


They have special-limit nickel-chromium K-type thermocouples. These respond quickly to changes in temperature, resist corrosion, and have an error margin of less than 0.4% instead of the typical 0.8%. However, for continual high-temperature high-precision professional use, they can be upgraded to platinum-rhodium S-types.


The US-international kilns don't come with a shelf, or posts, or kiln wash. However, so that you can start work straight away, our UK-EU kilns come with a pro shelf kit included in the price: a solid tough cordierite shelf, props, and kiln wash. It isn't a £40 extra.

A durable heavy cordierite shelf resists thermal fracture, provides a smooth stable work surface, protects the floor of the kiln's interior from glass accidents, and helps to even out any small temperature deviations during annealing, enamelling, firing, fusing, and heat treating as the elements turn on and off.

A UK reseller recommended using one shelf on three 50mm posts, not four 12mm. 50mm posts waste internal space and the shelf, with your work, balanced on three posts might tip: there is a good reason why chairs and tables have four legs.


For help, or in the unlikely event of a fault, you can mail or call an engineer in the UK. However, checks, adjustments, and repairs are simple, needing little more than a PosiDriv screwdriver: watch the on-line videos using the watch-videos link or read the help pages using use the help link, both below the menu bar near the top of any page. Alternatively, we can service the kiln in our workshop at Cherry Heaven.

Is A Paragon FireFly Kiln Going To Be The Best Long Term Choice?

The FireFly is a 1290°C kiln so it's hot enough to work with ceramics, glass, porcelain, and most materials and processes within its size and temperature limits. However, if you think that a front-opener, larger, or more specialised kiln might be more versatile, here are some suggestions:


Bead-annealing kilns generally have a maximum temperature of 650°C. For these, look at the BlueBird. However, other kilns have bead doors: the small 1290°C Caldera B and 1095°C SC2B, the medium 1290°C Xpress E12B, and the larger 925°C Fusion 14B. These are all hotter than the BlueBird, so more versatile.

Glass kilns generally have a maximum temperature of 925°C. For these, look at the F Series, Fusion:CS Series, GL Series, or Pearl Series. These are not hot enough for ceramics and porcelain.

Jewellery, silver clay, and enamelling kilns generally have a maximum temperature of 1095°C. For these, look at the small SC Series or the medium Xpress Series. The SC series are not hot enough for ceramics and porcelain.

Vitrigraph kilns generally have a maximum temperature of 1095°C. For these, look at the small Caldera or the medium Vitrigraph.

Ceramics kilns generally have a maximum temperature of 1290°C. For these, look at the small Caldera Series and FireFly Series, medium Xpress Series, or large Janus Series, PMT Series, and TNF Series. These can also be used for glass work.

Heat-treating kilns generally have a maximum temperature of 1095°C or 1290°C. For these, look at the HT Series and PMT Series. Although they look similar, the HT has a bottom-hinged door and the PMT has a side-hinged door.

Knife-making kilns generally have a maximum temperature of 1290°C. The KM Series are made for depth rather than width. You can choose a guillotine, drop-down, or a side-hinged door.

The W Series have a top vent so are usually used for jewellery moulds and lost-wax burnout. For lost-wax casting there are optional wax trays. The small SC Series and most of the medium Xpress Series also have top vents.


To learn more about these and other kilns, use the appropriate links below the menu bar near the top of the page. And remember that each series has kilns of different sizes with different options.

The UK-EU kiln is rated at 230V-240V 1560W, so it can use a regular mains socket. It's fitted with a switch that cuts off power to the elements when the kiln is opened: a UK-EU legal safety requirement. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 381mm x 470mm x 305mm high. The body has a 64mm high stand with four rubber feet. The hinged firebrick lid has a lifting handle and a stay-open prop. The shipping weight, including the box, is about 21Kg.

The firing chamber measures 203mm x 203mm x 114mm high, and heats from the back, sides, and front with the elements in dropped recessed grooves in the 64mm thick bricks. The kiln has an electro-mechanical relay and a nickel-chromium K-type thermocouple.

The programmer's electronic display prompts for heating rates, target temperatures, and hold times, making it easy to set up and re-use accurate heating, holding, and cooling sequences. The cone-fire mode, up to cone 10, will simplify your work with ceramics.

EXTRACTS FROM REVIEWS, AND MY OPINION

Reviews And Opinions.

The FireFly is a 1290°C cone 10 kiln so it's hot enough to work with ceramics, glass, porcelain, and most materials and processes within its size and temperature limits.

It's small enough to get out, use, and put away, it can stand anywhere, at 1680W it heats up quickly, and it has safety lid switch: so it's popular for classes, craft centres, jewellery studios, or home businesses, especially as it can use a regular 13A socket.


The FireFly is a top-opener. If you prefer a front-opener, still hot enough for ceramics and porcelain, look at the 1290°C Xpress Q11 or the larger Xpress E12.

For enamelling, fusing glass, or firing metal clays you might have looked at the Paragon SC2. However, as it's a 1095°C kiln, you won't be able to work with ceramics or porcelain. Remember that clay is cheap, or free: near us there are clay seams in the soil near the Southern end of Poole Harbour near Ferry Road.


The Caldera is slightly more expensive than the similar FireFly. However, it's 57mm taller inside and can accept clip-on collars between the body and the base. The Caldera X collar increases the internal height, the Caldera B collar increases the internal height and has a bead-annealing door, and the Caldera E collar increases the internal height and has an enamelling door. So it's a good idea to read about these before choosing?


Finally, a quote from a user: I am more than happy with my kiln: I'm thrilled with it. I bought the FireFly to graduate from torch-fired silver clay jewellery to stronger kiln-fired pieces. Not only has the kiln done a great job with silver clay but has proved to be super for bronze and copper clays as well. The digital controls are easy to use, and I have had no problems setting programs for all three types of metal clay. I am enjoying my retirement with my FireFly kiln. Thanks for such a great product.

The US-international kiln doesn't come with a shelf or posts or kiln wash. However, so you can start work straight away, there's a recommended kit, included in the price: one durable 178mm x 178mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of kiln wash. It's not a £35 extra.

The pro shelf resists thermal fracture, provides a smooth stable work surface, protects the floor of the kiln's interior from glass accidents, and helps to even out any small temperature deviations during annealing, enamelling, firing, and fusing as the elements turn on and off.

As the kiln only has top elements, I wouldn't recommend a second shelf as the lower shelf won't heat up in the same way and results might be unpredicatable.


However you arrange several shelves and their props, make sure that you don't box in the thermocouple or have the top shelf higher than the top element. If you need a little extra height, just put the bottom shelf in without its posts. Remember to use kiln wash on the shelves.

Whatever you choose, don't work directly on the floor of the firing chamber as any accidentally melted clay, glass, or metal will ruin the firebrick.

A UK reseller recommended using one shelf on three 50mm posts, not four 12mm. 50mm posts waste internal space and the shelf, with your work, balanced on three posts might tip: there's a good reason why chairs and tables have four legs.


The kiln is large enough to accommodate a 1-litre charcoal-filled stainless steel container needed to fire some makes of bronze clay and copper clay, both described on this internet resource.


The lost-wax burnout tray for this kiln measures 178mm x 178mm x 25mm. There are two parts: a stainless steel tray and a raised metal mesh that fits into the tray. The melting wax drops into the tray instead of onto the floor of the firing chamber. The mesh can also be used for supporting beads, enamelling, and fusing glass.

The FireFly W lid includes a 50mm x 50mm heat-resistant glass viewing-window in the centre. Otherwise it's the same as the FireFly lid. The window allows you to take a quick peep at china paints, enamels, glass, and glazes to check on their progress: and you might find it interesting or reassuring to watch what happens during firing.


If you look into a red-hot kiln, even briefly, it's important to wear glare-resistant glasses to protect your eyes from IR and UV radiation. Glare-resistant glasses are in the on-line shop.

A BRIEF INTRODUCTION TO CLAYS

Natural Clay.

What Is Clay?

Clays are formed naturally over millions of years as rocks break up into minute particles. They consist of hydrous aluminium silicates and other compounds such as feldspar, iron oxides, mica, and quartz. Clays are collectively referred to as ceramics.

Clays are often divided into three main categories: earthenware, porcelain, and stoneware. Generally, they needs to be fired for several hours, although the exact chemical composition affects the firing temperatures and times, and the clays' colour, porosity, shrinkage, and strength.

All clays are created to mature at specific temperatures, and any variance can lead to unsatisfactory results in ceramic durability or color. If fired too high, clay can deform or even melt; if fired too low, your pieces will be dry, rough, and potentially unsolidified.

Historically, low-fire has been the most commonly used firing range due to limitations in kiln technology. Modern kilns are now capable of much more complex, high-temperature processes, but low-fire range continues to be popular because it allows ceramic artists to use a variety of colourants that either burn off or become unstable at higher temperatures.

The maximum cone rating of a stoneware or porcelain clay is the temperature at which it vitrifies. This is the hardening, tightening and finally the partial glassification of the clay. Vitrification results from fusions or melting of the various components of the clay. The strength of fired clay is increased by the formation of new crystalline growth within the clay body, particularly the growth of mullite crystals. Mullite is an aluminum silicate characterized by a long needle-like crystal. These lace the structure together, giving it cohesion and strength.

When clay vitrifies it gets very strong. This is especially important for dinnerware where pieces are exposed to a lot of abuse. Vitrification also makes the clay's porosity low.

EARTHENWARE, PORCELAIN, AND STONEWARE

Earthenware Flower Pot.

What Are Earthenware, Porcelain, And Stoneware?

Earthenware is normally beige, red, or white. It has the lowest firing temperature of the three, usually lower than 1150°C. It's slightly porous, and stains and chips easily, so it's often glazed to protect the surface. Its porosity means it's good for making terracotta planters and oven steamers, but not good for jugs or vases.


Porcelain is composed of kaolin, or china clay. Kaolin doesn't melt until 1800°C, so other compounds are usually added so it can be fired between 1250°C and 1400°C. For example, bone china is made by adding bone ash to the clay. It's known for its whiteness, hardness, smoothness, durability, and translucency. When tapped, it makes a distinctive ping: or ming.

Named after a hill in China from which it was mined for centuries, kaolin is the purest form of clay and is the foundation of all porcelain clay bodies. Though pure kaolin clays can be fired, often they are mixed with other clays to increase both workability and lower the firing temperature, so if using a kaolin-based clay body, be sure to note how pure your material is, as this will change the required temperature.

As a clay body, porcelain is known for its hardness, extremely tight density, whiteness, and translucence in thin-walled pieces. Another difficulty with porcelain bodies is that they are very prone to warping during drying in the kiln

When fired, porcelain becomes a hard, vitrified, non-absorbent clay body, very similar to high-fire stoneware. It also develops a body-glaze layer formed between the clay body and the glaze. The absence of any iron, alkalies, or alkaline earths in the molecular structure of kaolin not only dictate its high-fire requirements, but are also responsible for its most identifiable characteristic: its white color.


Stoneware is normally beige, grey, or red-brown. It's usually fired between 1150°C and 1300°C. It's hard, durable, and resists thermal shock. Glazes bond well, so it can be made waterproof.


Stoneware is a plastic clay, often grey when moist. Getting its name from the dense, rock-like nature of the clay body when fired, stoneware is typically combined with other clays to modify it, such as ball clays which might be added for plasticity. It is important to note that stoneware is divided into two types: mid-fire and high-fire.

Like low-fire bodies, mid-range stoneware is relatively soft and porous and has a clearly separate glaze layer after firing. However, a mid-range firing results in increased durability of the ware as well. When fired, stoneware ranges in color from light grey to buff, to medium grey and brown.

Mid-range glazes typically mature between Cone 4 and Cone 6, and most commercial underglazes have a maximum temperature of Cone 6. These glazes are more durable, still offer a fairly extensive color range, and though not quite as harsh as low-fire glazes, can still be quite bright.

BISQUE

Bisque.

What Is Bisque?

Bisque is clay which has been fired once, without a glaze, to a temperature just before vitrification. Firing changes the clay into ceramic material, without fully fusing it. A second, slower, firing melts the glaze and fuses it to the clay body.

BONE CHINA

Royal Victoria Bone China Cup And Saucer. Wedgewood White Dinner Set. Rose Bouquet Dessert Plates. Royal Albert Bone China Tea Set.

What Is Bone China?

Bone china is a type of porcelain composed of bone ash, feldspathic material, and kaolin. It's the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency. Its high strength allows it to be produced in thinner cross-sections than other types of porcelain.

From its initial development and up to the latter part of the 20th century, bone china was almost exclusively English, with production being effectively localised in Stoke-on-Trent. Most major English firms made or still make it, including Fortnum & Mason, Mintons, Coalport, Spode, Royal Crown Derby, Royal Doulton, Wedgwood, and Worcester.

In the UK, references to china or porcelain can refer to bone china, and English Porcelain has been used as a term for it, both in the UK and around the world.

POLYMER CLAY

Polymer Clay Flowers By Olga Zhukova. Polymer Clay Key Rings. Polymer Clay Beads By LiasonWithAlison. Polymer Clay Necklace By Facet Jewellery.

What Is Polymer Clay?

Polymer clay is a man-made material: tiny particles of polyvinyl chloride mixed with plasticisers and pigments. When it's baked, at around 125°C, the particles fuse and the clay hardens.

RAKU

Raku By Lori Duncan. Raku By Brian Seckinger. Raku By Greenwich Community College. Raku By Soley Ceramics.

What Is Raku?

Raku was originally a Japanese technique, but it's now become an internationally popular way to make decorative ware, with each piece having a unique blend of colours.

A bisque piece is fired to about 950°C, then glazed. It's removed from the kiln when red-hot, and put straight into a container of combustible material.

The flames, reducing atmosphere, and mix of chemicals stain the clay. When the piece is removed and quenched in cold water, interesting colours and shades remain: often unpredictable.

A BRIEF INTRODUCTION TO GLASS AND GEMS

Obsidian. Fish. Curved Glass by Infabbrica. Lauscha By Carrie Fertig.

What Is Glass?

The main component of glass is silicon dioxide, often called silica: found naturally and plentifully as sand. When it melts, at around 1700°C, it's like syrup on a cold day. When it cools, it forms a rigid brittle glass called quartz glass.

To lower the melting point, and reduce the cost of melting, chemicals are added: typically sodium carbonate and calcium oxide. Other chemicals, and different heating and cooling processes, produce a range of colours and mechanical properties.

Chemically, glass is defined as an amorphous solid but, as it's heated, it becomes softer allowing it to be blown, cast, coated, decorated, engraved, heat-treated, moulded, poured, pressed, sagged, and slumped.

A form of glass occurs naturally within the mouth of a volcano when the intense heat of an eruption melts sand to form Obsidian, a hard black-to-brown glassy type of stone, shown in the photo. Although it was used decoratively, when it fractures it has very sharp edges, many times sharper than a steel knife-edge, so was also used for tools and weapons: and the pitiful rituals of circumcision and female genital mutilation.

ANNEALING
Annealed Beads Made Into A Necklace.

What Is Annealing?

Very briefly, annealing generally involves heating glass or metal to it's annealing point, maintaining a specific temperature for a set time, and then cooling it to room temperature.

During annealing, fabrication stresses are relieved as the molecules cool and arrange themselves into a regular stable matrix. Successful annealing is the key to creating work that will remain attractive and durable. It can be quite a long process, and involve multiple phases, so a kiln with an automatic comprehensive programmer is essential.

You can download, and print, a Bead Annealing Guide. Paragon created it in 2013 so it's only a guide, not a contemporary definitive document. Click here. It's a pdf file, but your device should already have a pdf viewer.

BOILED GLASS
Boiled Glass.

Glass scraps, with optional bubble powder, are put in a tray or a mould and heated. As the temperature increases the glasses begin to bubble. The bubbles mix the colours and give a natural organic appearance. The glasses need to be compatible as different colours and expansion coefficient might not work, so the boiled glass technique needs experiment and practice.

You increase the temperature at about 300°C per hour to 925°C with no bubble squeeze and soak for 10–15 minutes. Then allow the kiln to drop the temperature as fast as possible to about 815°C and soak there for around 30 minutes to allow the little bubbles to rise to the surface and burst. Then reduce to the annealing temperature and soak for the thickness you calculated in preparation for the firing.

CUBIC ZIRCONIA
Cubic Zirconia.

What Are Cubic Zirconia.

Cubic Zirconia is the most popular substitute for a diamond because they look almost dentical. Cubic Zirconia or CZ, is made from zirconium dioxide which comes closer than any other gem to matching the characteristics of a diamond. It's not quite as hard as diamond and is slightly less sparkly but displays more prismatic fire with more colour sparkles within the gem, especially if metal oxides are added during the production process.

Caring for CZ is important because they are more brittle than diamonds and susceptible to wear and tear such as chipping and scratches over time.

DECALS
Rose By Arwen Moore Design.

What Are Decals?

A decal or transfer is an image or pattern printed on a ceramic, cloth, paper, or plastic substrate that can be moved on to another surface, usually with the aid of water and heat.

A wet decal can be slid into position, allowed to dry, and then heated in a kiln. Most ceramic decals come with a cone number for easy firing, typically cone 022. The programmer on the Paragon Fusion 7XL has pre-set cone numbers as well as the normal ramp-hold options used for general glass work.

Decals are a quick and fun way to decorate bottles, glasses, and vases, as most low-fire ceramic decals and low-fire glass decals will work very well, even on float glass.

DIAMONDS
Diamond.

What Are Diamonds?

Diamonds are not a form of glass: they're naturally occurring gems composed of carbon atoms arranged in a very regular pattern.

Between 1 billion to 3.3 billion years ago, simple carbon containing trace minerals was transformed into diamonds by heat and pressure at depths of over 100 miles below the earth’s surface. We can’t mine down far enough to reach the earth’s mantle but fortunately volcanic eruptions brought the diamonds closer to the surface. They're extremely hard and until recently were regarded as the world's hardest natural material.

Although diamonds are extremely expensive, their price is governed by carat, cut, colour, and clarity. It’s very rare to find a diamond that doesn’t contain flaws: however the impurities, and internal refraction and dispersion of light, give diamonds their brilliance.


Synthetic diamonds are manufactured and are identical in hardness, dispersion, gravity, refraction and chemical composition to the highest quality mined diamonds available. Whereas a one-carat top quality diamond would cost thousands of pounds to buy, the same quality man-made diamond could be made for less than £5.

This will obviously have a huge impact on the diamond industry over the next few years as when comparing a cultured and mined diamond side by side they are virtually undistinguishable. A bit like pearls, they can be grown from a single crystal using chemical vapor deposition.

DICHROIC GLASS
Dichroic Glass.

What Are Dichroic Glasses.

Dichroic glass has two different colours: a transmitted colour and a reflective colour, both of which change depending on the angle of view. For example blue-red will be blue in transmission and red in reflection.

During manufacture, quartz and metal oxides are vapourised onto the surface of the glass using a vacuum deposition process, forming a multi-layer crystal structure.

ENAMELLING
Enamelled Jewellery.

What Is Enamelling?

Enamelling involves applying a glass paste to metal and then heating it to fuse it to the surface. The finish of the enamel can be translucent or opaque depending on the temperature used to melt the glass. Higher temperatures result in a more transparent and durable enamel whilst lower temperatures give a more opaque and fragile surface. Dyes and pigments can be included to produce any colour.

The Paragon SC2 is ideal for enamelling, although other kilns are fine. So click the sc2-sc3:jewellery link below the menu bar near the top of the page. The SC-2W and SC-3W doors include a 50mm x 50mm heat-resistant glass viewing-window in the centre of the door, allowing you to take a quick peep at china paints, enamels, glass, and glazes to check on their progress

FIRE POLISHING
Fire Polished Glass.

What Is Fire Polishing?

To fire polish glass, return the items to the kiln and melt them just enough to give a smooth polished appearance. It needs a temperature of around 700°C, and is often used to round the edges of glass after fusing.

Fire polishing already-slumped items is more difficult because the polishing temperature is close to the slumping temperature and it can distort the appearance of the piece. So it generally works best for flat items, rather than slumped ones. It has the slight limitation that the part of the item that touches the kiln shelf won't polish.

FUSING, SAGGING, AND SLUMPING
Fused Glass.

What Is Glass Fusing?

If two or more pieces of glass in contact are heated, they begin to soften and fuse together. With careful heating and cooling, the separate pieces of glass become one.

If glass is put on a mould and heated, it begins to soften and collapse, or sag, onto the mould: a common technique for making bowls and plates.

Sagging and slumping are often thought of as being the same. Correctly: during sagging, heated glass, supported at its edges, sags down in the middle to conform to a mould; during slumping, heated glass, supported at its middle, slumps down at its edges to conform to a mould.

LAMPWORK AND BEADS
Beads.

What Is Lampwork?

Lamp-working is the traditional name for glasswork that uses a flame to melt glass rods and tubes. As the glass softens, it's shaped by turning and using tools.

Early lampworkers used an oil-lamp, and blew air into the flame through a pipe. Later, propane, natural gas, or butane torches replaced the lamp, although kilns are now increasingly popular, particularly for annealing.

Beads are usually made on steel rods, or mandrels. When the beads are finished, the rods are removed leaving holes for threading the beads. Cold working techniques can be used, such as etching, faceting, polishing, and sandblasting.

LOST-WAX BURNOUT
Paragon W13 Lost Wax Casting Kiln With A Sentry Programmer.

What Is Lost Wax Burnout And Casting.

Lost-wax burnout starts with making a wax shape and then making a mould of the shape. When the mould is heated in a kiln, the wax melts out through channels, usually over a burnout grate and into a tray. The shape is then cast in glass or metal from the mould.

It's important to prevent wax or carbon sticking to the elements, so burnout kilns have a top vent to release the fumes. Carbon build-up inside a kiln conducts electricity and can cause the elements to short circuit.

I've written some general instructions here but, as always, making anything successfully needs critical research and frequent tests, especially as things that work for your friends and teachers might not work in the same way for you. It's also very important to learn how to creatively use unexpected effects.

The most popular kilns for lost wax processes are the Paragon W series: the W13, W14, and W18. Learn about these by using the w:lost-wax-burnout link below the menu bar near the top of the page. Wax burnout trays, glare-resistant glasses, and heat-resistant gloves are in the on-line shop.

HOW TO DO LOST WAX BURNOUT

How To Do Lost Wax Burnout And Casting.

1 : Place a metal tray inside the kiln on a few 12mm posts. Place the mould on a grate on top of the tray. The mould’s sprue holes should face down. The tray will catch melting wax as it drips from the sprue holes.

2 : Keep the kiln’s vent hole open during wax elimination. If the kiln has no vent hole, leave the door open 12mm. This allows fumes to escape from the kiln. Heat the kiln to 148°C and hold it at that temperature for at least one hour. Do NOT heat the wax above 148°C.

3 : During this hour, the wax will melt from the mould and drip into the tray. If the kiln gets hotter than 148°C, the wax may smoke and deposit carbon inside your kiln, causing expensive damage.

4 : After one hour at 148°C, open the kiln. Remove the mould and wax tray. Pour the wax from the tray and leave the tray out of the kiln until your next wax elimination. Don't leave the tray in the kiln.

5 : Harden the mould to the temperature recommended by your mould material manufacturer.

6 : Finally, adjust the temperature to the casting temperature of the glass or metal. Hold at that temperature until you are ready to begin casting. Remove the mould with tongs. Wear protective gloves and safety glasses.


Over time, a small amount of carbon can form on the firing chamber walls as any wax residue left in the mould burns off. So I recommend that you periodically open the vent or leave the door open 12mm, and fire the kiln empty to 815°C at a rate of 166°C with a one hour hold.

MOISSANITE
Moissanite.

What Is Moissanite.

Moissanite is another diamond substitute which is a rare mineral found naturally in small quantities, although Moissanite for jewellery is artificially made. It’s made from Silicon Carbide which means it’s able to withstand high temperatures and is very hard.

Moissanite is noticeably much sparklier and displays more prismatic fire than a diamond which is noticeable even to an untrained observer. Moissanite does have inclusions like a diamond and it may also have a greenish tinge to its colour.

PÂTE DE VERRE
Pâte De Verre.

What Is Pâte De Verre?

Pâte de verre involves making a glass paste, applying it to a mould, firing it, and removing the piece from the mould. The glass paste is usually made from glass powder, a binder such as gum arabic, distilled water, and colouring agents or enamels. It allows precise placing of colours in the mould, whereas other techniques often result in the glass straying from its intended position.

I think, currently, Daum is the only large commercial crystal manufacturer using the pâte de verre process for art glass and crystal sculptures.

SLUMPING BOTTLES
Slumped Bottle.

What Is Glass Slumping?

This a simple technique but it requires good ideas. A bottle, such as those used for wine, beer, cola, or champagne, is softened in a kiln so that it begins to flatten out or conforms to a mould. There are too many moulds to stock here but there are lots available on line. Or make your own from clay.

The bottles need to be clean and dry, with all paper labels and tops removed. Put them in your kiln on a shelf, either with shelf paper or kiln wash to prevent the glass sticking to the shelf.

Paragon makes a kiln designed for this: the Trio. So click the trio link below the menu bar near the top of the page. It's wide enough for most bottles but can still use a regular socket.

STAINED GLASS
Stained Glass.

What Is Stained Glass?

Stained glass is glass that has been coloured by adding metallic salts during its manufacture. The coloured glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, traditionally held together by strips of lead and supported by a rigid frame. Painted details and yellow stain are often used to enhance the design.

The term stained glass is also applied to windows in which the colours have been painted onto the glass and then fused to the glass in a kiln.

It requires artistic skill to conceive an appropriate and workable design, and engineering skills to assemble the piece. A window must fit snugly into the space for which it is made, must resist wind and rain, and also, especially in the larger windows, must support its own weight. Many large windows have withstood the test of time and remained substantially intact since the Late Middle Ages.

SWAROVSKI CRYSTAL
Swarovski Crystal.

What Is Swarovski Crystal?

Swarovski Crystal isn’t a gemstone or even a crystal: it’s a form of glass made at high temperatures by melting silicon oxide powders with lead to form what is known as lead crystal. The exact process is patented by Swarovski but it has approximately 32% lead content to increase the crystals refraction index to resemble that of a diamond. To produce a diamond like effect the crystal glass is precision cut and then polished again by a Swarovski patented process that gives the crystal a high quality finish.

The crystals are often further enhanced by coating the glass with an Aurora Borealis or AB coating that gives the surface a rainbow like appearance to simulate dispersion from a diamond. Swarovski crystal is not as hard as diamond so its susceptible to scratches and chipping from wear and tear, but it’s harder than standard glass.

TACK FUSING
Tack Fused Glass.

What Is Tack Fusing?

Tack fusing is the joining together of glass, with as little change to the shape of the pieces as possible. Tack fusing may be used either decoratively, or to assemble a large piece of glass from laminations.

Where tack fusing is used to apply small decorative details to a larger piece, you might want to partially melt the small pieces so that they change shape, usually becoming more spherical under the influence of surface tension, but without changing the shape of the carrier piece. This can be done by using an increased temperature, but only briefly. The carrier piece has a larger thermal mass, so heats up more slowly than the small decorations.

VITRIGRAPH WORK
Glass Stringers. Paragon Caldera Kiln With A Sentry Xpress Programmer For Vitrigraph. Ceramic-Fibre Boards. Crucible.

What Is Vitrigraph?

The vitrigraph process usually uses a Paragon Caldera kiln to make glass stringers. The clip-on bottom of the kiln is removed and set aside. The kiln body is put on a thick ceramic rectangle with a central hole. The rectangle is put on two wall brackets or any stable structure away from the floor.

A crucible of glass is put in the kiln and, as it heats, the moulten glass falls through a hole in the crucible to form long stringers. Skilled artists can control the thickness of the stringers and can even draw with the glass as it comes out.


The Caldera needs a 500mm x 400mm x 50mm rectangle, which we cut for you from a much larger sheet. Normal kiln shelves are made from cordierite: a very dense hard ceramic. A suitable-size rectangle would be fairly heavy and hard to cut and drill, so we we use ceramic-fibre board. Ceramic-fibre rectangles are in the on-line shop.

Ceramic-fibre board is made from vacuum-formed fibre. It doesn't retain heat, has a low thermal conductivity, and is stable at temperatures up to 1430°C. If you need to trim it, use a knife, handsaw, or electric jigsaw, but cut it neatly because, as it's fibrous, you can't use a file or sandpaper successfully.


When you work with any fibrous material, don't get the fibres on your hands or breathe them in: ideally, you should put on gloves, wear a HEPA dust mask, use clear protective glasses, and wash your hands afterwards.

WARM GLASS
Warm Glass Flower Bowl.

What Is Warm Glass?

The term warm glass refers to fusing, slumping, and other glass processes which take place at temperatures between about 600°C to 925°C. Although that doesn't sound warm, it is when you compare it to glassblower's working temperatures, which often exceed 1100°C. Warm glass is sometimes called kiln-formed glass.

A BRIEF INTRODUCTION TO METAL CLAYS
Art Clay Silver Clay. Acrylic Tools. Clay Shapers. Hand Tools.

What Is A Metal Clay?

Metal Clays are clay-like materials made of fine metal powders and water-soluble organic binders. Out of the packet they feel like modelling clay, so can be shaped using anything appropriate. If you don't like what you've made, you can roll it up and start again. Any scraps can be wrapped up in cling-film or foil and re-used, so there's almost no waste.

When you're happy with your work, it's dried so that the moisture can evaporate. At this stage it feels like a plaster, so you can still refine the shape: or even add more clay.

As it's fired, the binders vapourise, releasing small amounts of non-toxic carbon dioxide and water, and the metal powder sinters, leaving solid metal: real metal, not something that just looks like metal. The firing temperature isn't high enough to melt the metal otherwise your work would liquify and lose it's shape.


Although Art Clay and PMC silver clays were first to market, there's now an increasingly diverse range of metal clays, such as Cinter, Clay Mania, Creative, Goldie, Hadar Jacobson, Metal Adventures, Meteor, Noble, PMC Sterling, and Prometheus.

I sometimes get asked if there's a platinum metal clay: there is, but it's an industrial product. Platinum melts at 1772°C, so a platimum clay would probably need to fire at around 1600°C: beyond the maximum temperature of conventional kilns.


All our tools have been chosen for their engineering excellence and clean functionality, to help you manage a creative and efficient work environment. And you'll enjoy using good tools rather than continually improvising. To learn more, use the accessories-tools link below the menu bar near the top of the page.

SILVER CLAY
Art Clay Silver Pendant. Art Clay Silver Necklace. Art Clay Silver Pendant. Art Clay Silver Brooch.

Aida Art Clay Silver And Mitsubishi PMC Silver Clay.

There are two popular makes of silver clay: Art Clay made by Aida Chemical Industries and PMC made by Mitsubishi Materials Corporation, in Japan. They're both clay-like materials made of fine silver powder and water-soluble organic binders.

Art Clay Silver and PMC Silver, sometimes just called silver clay, metal clay, or precious-metal clay, are easy to fire: put your dried work on a kiln shelf and programme the temperature and hold-time.

As they're fired, the binders vapourise, releasing very small amounts of non-toxic carbon dioxide and water, and the metal powder sinters, leaving solid 999 silver: real metal, not something that just looks like metal.

All jewellery kilns include a durable shelf kit so that you can start work straight away, but several shelves can be stacked to make better use of your time and reduce the unit-cost of firing: so you might want more than one.


Although we chose to work with, sell, and provide classes in Art Clay, both makes fire in a similar way. So any kiln suitable for Art Clay will be just as good for PMC.

If you're currently using PMC, try Art Clay. There are differences in the feel, the shrinkage, the strength, the surface lustre, the product range, the pricing, and the general commercial setup if you're running a serious business.

BRONZE CLAY
Bronze-Copper Lobster Bangle By Gordon Uyehara.

Bronze Clay And BronzClay.

There are three popular makes of bronze clay: Bronze Clay made by ClayMania, BronzClay made by Metal Adventures, and Prometheus Bronze ProClay made by Odak. They're all clay-like materials made of fine bronze powder and water-soluble organic binders. However, they're fired in different ways:

Prometheus Bronze Clay is easy to fire: wrap your dried work in kitchen tissue or ceramic cloth, put it on a kiln shelf, and programme the temperature and hold time. It can also be fired in charcoal.

Clay Mania Bronze Clay and MetalAdventures BronzClay fire in a special way. Fired normally, the surface would oxidise so, to minimize this, they're embedded in activated charcoal granules in a covered stainless steel container. Charcoal made from coconut shells produces a natural bronze colour, and charcoal made from coal produces a colourful range of patinas.

As they're fired, the binders vapourise, releasing very small amounts of non-toxic carbon dioxide and water, and the metal powder sinters, leaving solid bronze, an alloy of 89% copper and 11% tin: real metal, not something that just looks like metal.


The stainless steel container for the Paragon SC-2 measures 162mm x 176mm x 100mm high, and holds 1 litre of charcoal. To fire larger pieces, or more pieces at the same time, you'll need a larger kiln, such as the Paragon Xpress E-12A. The container for the E-12A measures 265mm x 162mm x 152mm high and holds 3 litres of charcoal.

The 1230°C firebrick E12A costs more than the 1095°C ceramic-fibre SC2. However, it's two and a half times larger than the SC-2 and is a versatile mixed-media kiln suited to continual high temperatures.

Particulates represent a health risk if they're breathed in, so wear a HEPA mask when cleaning out your kiln, mixing kiln wash, and working with charcoals, ceramic-fibre blocks, cloths, and papers. And, ideally, use protective glasses.

All jewellery kilns include a durable shelf kit so that you can start work straight away, but several shelves can be stacked to make better use of your time and reduce the unit-cost of firing: so you might want more than one.


I can't recommend one clay as being the best. There are differences in the feel, the firing, the shrinkage, the strength, and the surface patinas, so try them and experiment: they're not expensive.
However, as Prometheus Bronze Clay is easy to fire and costs less than the others, try it first? It comes as 100gm of soft clay in a packet, or 10gm of creamy clay in a syringe with three tips that you can cut or shape.

There's also Creative Bronze, which is almost certainly Prometheus Bronze Clay renamed. I'll leave it you to work out why very similar products can differ so much in price.


Also, in November 2014, 100gms of Art Clay Silver Clay costs about 12 times more than Prometheus Bronze Clay. So, if you're still in the learning phase, you can try out ideas before possibly wasting your expensive silver clay. However, bronze is a beautiful metal so, as with many materials, you need to exploit its qualities and try to produce beautiful original pieces.

COPPER CLAY
Copper Earring By Zina Kuscynska Richterova.

Copper Clay And CopprClay.

There are four popular makes of copper clay: Art Clay Copper made by Aida Chemical Industries, Copper Clay made by ClayMania, CopprClay made by Metal Adventures, and Prometheus Copper ProClay made by Odak. They're all clay-like materials made of fine copper powder and water-soluble organic binders. However, they're fired in different ways:

Aida Art Clay Gold And Mitsubishi PMC Gold Clay.

There are two popular makes of gold clay: Art Clay made by Aida Chemical Industries and PMC made by Mitsubishi Materials Corporation, in Japan. They're both clay-like materials made of fine gold powder and water-soluble organic binders.

Art Clay Gold and PMC Gold, sometimes just called gold clay, metal clay, or precious-metal clay, are easy to fire: put your dried work on a kiln shelf and programme the temperature and hold-time.

As they're fired, the binders vapourise, releasing very small amounts of non-toxic carbon dioxide and water, and the metal powder sinters, leaving solid 22 carat gold: real metal, not something that just looks like metal.
