The Paragon Trio kiln for slumping bottles, and general glass annealing, casting, fire polishing, fusing, lampwork, melting, moulding, sagging, and slumping.

Paragon Trio kilns are generally used for slumping glass bottles, and annealing, casting, fusing, melting, moulding, sagging, and slumping glass, although they have other applications. They're 925°C kilns with digital programmers, in Paragon blue or customised berry, black, jade, navy, pink, purple, or turquoise. Learn about the Paragon Trio kilns on this page.


There are two versions: the Trio and the Trio W. The W version has a heat-resistant glass viewing-window in the middle at the front.


Every version is 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. However, it's only the control boxes that are painted: not the whole kiln. Customised kilns are made to order, so can't be returned if the colour isn't exactly as in the photo.


They normally have the popular Sentry Xpress 3-key programmers. Features include twenty-five free-to-set sequences, each one with up to twenty segments.

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 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 elements are in dropped recessed grooves in the 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, these can be upgraded to platinum-rhodium S-types.


The US-international kilns don't come with a shelf or posts or kiln wash so, if you don't need a shelf, you won't have to pay for one. However, I've recommended pro kits because 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 changes during annealing, enamelling, firing, fusing, and heat treating as the elements turn on and off.


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 Trio Kiln Going To Be The Best Overall Choice?

The Trios are classed as glass kilns, so hot enough, at 925°C, for slumping bottles and general glass work, within their size limits. The flat-bed CS and Fusion kilns are similar but larger. However, if you think that a smaller, larger, or hotter 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 metal grids and 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.

Paragon Trio Kiln With A Sentry Xpress Programmer For Annealing, Bottle Slumping, And General Glass Work. Paragon Blue Or Customised Berry, Black, Jade, Navy, Pink, Purple, Or Turquoise. Orton-Paragon Sentry Xpress Programmer.

The Paragon Trio kiln for slumping bottles, and general glass annealing, casting, fire polishing, fusing, lampwork, melting, moulding, sagging, and slumping.

The Paragon Trio is a 925°C, square, plug-in, top-opening, table-top, firebrick kiln with a ramp-hold Sentry Xpress 3-key programmer. Choose Paragon blue or customised berry, black, jade, navy, pink, purple, or turquoise.


The UK-EU kiln is rated at 230V-240V 1800W, 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 787mm x 584mm x 457mm. The case has an integral stand with four rubber feet and the lid has a stay-cool wooden handle. The shipping weight, including the crate, is about 54kg.

The firing chamber measures 451mm x 273mm x 165mm high, and heats from the top, with the elements in dropped recessed grooves in the 76mm thick bricks. The kiln normally 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.

EXTRACTS FROM REVIEWS, AND MY OPINION

Reviews And Opinions.

Although the internal sizes are suited to slumping two champagne, spirit, or wine bottles, it's also a versatile glass kiln for your craft workshop or glass studio. It's popular with glass artists, for annealing, casting, fusing, melting, moulding, sagging, and slumping. In the US, it used to be called the Fusion 17.

THE PARAGON TRIO: KILN FURNITURE

Shelf Kits For The Paragon Trio Kiln.

The US-international kiln doesn't come with a shelf or posts or kiln wash. However, there's a recommended kit, not included in the price: one durable 432mm x 254mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of kiln wash.

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, fusing, and heat treating as the elements turn on and off.

Depending on the material or process, and the sizes of your pieces, stacked shelves will hold more work, free up your time, and reduce the unit firing cost, so there's an extra recommended kit, not included in the price: one 432mm x 254mm x 15mm shelf and four posts. The kiln normally has room for two shelves so you can choose 12mm, 25mm, 50mm, 75mm, or 100mmm posts.

Remember that the kiln only has top elements, so an upper shelf might box in the thermocouple or be at a different temperature than the lower shelf.


The kiln is large enough to accommodate a 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 burn-out tray for this kiln measures 279mm x 190mm x 25mm. There are two parts: a stainless steel tray and a metal mesh that fits into the tray. The melting wax drops into the tray instead of onto the floor of the kiln. The tray and mesh can also be used for supporting beads, enamel work, and fused glass.

THE PARAGON TRIO W: WINDOW

BOTTLE SLUMPING, AND GLASS ANNEALING, FUSING, AND SAGGING
Paragon Trio W Kiln With A Window And A Sentry Xpress Programmer For Annealing, Bottle Slumping, And Glass Work. Paragon Blue Or Customised Berry, Black, Jade, Navy, Pink, Purple, Or Turquoise. Orton-Paragon Sentry Xpress Programmer.

The Paragon Trio W kiln with a window for slumping bottles, and general glass annealing, casting, fire polishing, fusing, lampwork, melting, moulding, sagging, and slumping.

The Paragon Trio W includes a 75mm x 25mm heat-resistant glass viewing-window in the centre of the front. Otherwise it's the same as the Trio.

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 the firing sequence.
The window will cause a modest heat loss so the kiln might not heat as quickly or reach its top temperature. To resolve this, tuck a piece of ceramic-fibre cloth behind the glass. Ceramic-fibre cloths are in the on-line shop.


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

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.

FREE BEAD ANNEALING GUIDE

A Bead Annealing Guide.

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 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 mesh 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 fumes. Carbon build-up inside a kiln could conduct electricity and would eventually cause the elements to fail.

Paragon make kilns designed for this: the W series. So click the w:lost-wax link under the menu bar near the top of the page. They all have top vents and optional wax trays.

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

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.
