Firing is how Art Clay turns into pure silver. This is where it all happens. Everything else you have done has been a prelude to this little bit of technological alchemy. No matter which method you use to fire Art Clay, the process is the same: burning the organic binders off and sintering the silver particles to increase strength. In the end, you have a piece of 99.9% fine silver, just 8-9 percent smaller and with all the fine detail and shape of the pre-fired piece.
If you have a gas stove in your kitchen or portable camping stove, this is the most convenient and inexpensive method of firing Art Clay Silver. All you need is a stainless steel net large enough to settle and balance the piece on the stove burners, a pair of tweezers, and a timer.
Firing Art Clay Silver with a gas stove uses a direct flame. This method works best for small and simple pieces. You can fire pure silver findings and small gemstones (5mm or under) with this method. Items that cannot be fired with this method include projects made using Cork Clay, paper, or large quantities of organic material, and projects that include glass, ceramic or porcelain. Using these instructions, you can fire Art Clay Silver Series creations. There is a size limitation for this method. You may fire creations that are no larger than 5.0cm (L) ×3.0cm (W) ×2.0cm (H), and weigh up to 30gm.
1. Firing on a Gas Stove
Place the stainless net on the cooking stove burner. Turn on the cooking stove. Confirm the most red-hot part on the stainless net.
Turn off the cooking stove once again. Place the piece where the most red-hot part was using a pair of tweezers. Cover the piece with the stainless cage.
Turn on the cooking stove again and fire the piece for five minutes. You will see that the piece starts turning an orange color during heating. Turn off stove and cool for at least 20 minutes.
2. Gas Torch Firing
Place a fiberboard on a fire brick. Place the piece on the fiberboard.
Switch on the gas torch.
Hold the torch and fire the piece evenly. When the piece turns orange, continue to fire the piece keeping the same color for the appropriate firing time.
3. Kiln Firing
Put the piece (on a fiber board) into a kiln. Turn on the switch and program the kiln to an applicable firing temperature.
When the temperature is reached, hold for the appropriate holding time.
Turn off the kiln after the holding time. Take out the piece when cold.
This type can be modeled in the same way as regular water-based clay. Once opened, it is susceptible to the air and must be kept moist in order to retain its pliability and workability. Use a container of water and a paintbrush to moisten any areas of the clay surface that begin to crack while working.
The only difference between Paste type and Clay type is the amount of water portion in the mixture.
Paste type comes in the consistency of melted ice cream and you should only transfer the amount needed from the jar to a small tray and dilute with water to create the desired thickness.
It is used in several ways:
- As a glue to join two pieces of dry or wet clay together.
- As a gap-filler for pits and cracks that appear in dried pieces.
- To attach silver findings (screw eyes, bailbacks, brooch findings, etc.) to dried or wet clay pieces. During firing, the normal contraction of the clay bonds the findings.
- When applied in separate layers onto organic forms such as leaves, dried flowers, paper-origami, etc, Paste type creates a perfect impression of the form.
Art Clay Silver Syringe type is 5gm and 10gm of Art Clay Silver in a pre-loaded syringe. Syringe type comes packaged in three ways: with color-coded tips (blue, green and gray), each an increasingly larger diameter; a one tip (green nozzle) package; and packaged without any tips. Each of the tips is reusable and only needs to be purchased once. The diameter of each syringe nozzle is; Blue Nozzle: 0.41mm, Green Nozzle: 0.84mm, and Gray Nozzle: 1.19mm. The consistency of Syringe type is totally different from that of Paste type and it is not to be thought of as just paste in a syringe. Syringe type is thicker, more controllable and allows more workability. It is used in several ways:
- To decorate pieces, much like using cake decorating tips. Lines, filigree, faux cloisonné borders, and even hollow balls can be made with Syringe type.
- As a repair “glue” to fill cracks and gaps.
- To attach findings to wet or dry clay pieces.
Art Clay Silver Oil Paste type
Art Clay Silver Oil Paste is an oil-based paste and it is formulated to act as a bond between fired silver pieces. Oil Paste provides a solid weld between pure silver findings, or between two fired pieces. It comes in two separately sealed jars. One has 10gm of very thick paste, the other contains a thinner that is used to keep the paste at working consistency. Both jars must be kept tightly capped. Silver findings also can be attached to the piece with Oil Paste, and then re-fired for adhesion. Fires at 800℃ / 1472˚F for 30 minutes or 850℃ / 1562˚F for 10 minutes.
Overlay Silver Paste
This Art Clay product is specifically formulated to bond to non-porous or glazed surfaces such as ceramic, porcelain, and glass. Overlay Silver Paste can be used in a variety of ways:
- Paint directly, full strength, onto bisque, glazed porcelain or glass pieces.
- Used in a technique called sgraffito, whereby a thin layer of Overlay paste is applied to the glazed porcelain or glass, allowed to dry, and then a pointed tool is used to scratch a design into the layer so that the porcelain or glass beneath appears, giving a stenciled look. This product is fired at 650℃ / 1202˚F for 30 minutes.
The Art Clay Silver Slow Tarnish (or ST) series comes in three basic forms, Clay type, Paste type and Syringe type. Silver products, whether they are made of pure silver or sterling silver (SV925 or 950) have a tendency to tarnish due to the chemical reaction between the metal and the air. Although Art Clay products tarnish slower than sterling silver, a piece made of ST series tarnishes even slower than any other Art Clay series products. A piece made of Slow Tarnish clay can maintain its shine even longer with regular jewelry cleaning. The ST series remains 99% high quality silver after firing. It fires at one temperature setting of 800℃ / 1472˚F for 30 minutes..
Art Clay Gold Clay is a water-based gold clay that can be modeled in the same way as with the other Art Clay series products. It will transform to high quality 22-Karat gold after firing and
contracts about 15% during the firing process.
Fire at 990℃ / 1814˚F for 60 minutes. Available in 3 gram packs of clay.
Paste type Art Clay Gold Paste comes in a viscous liquid form, so that you can add texture or draw directly on the surface of Art Clay Silver (fired piece), ceramic, porcelain and/or glass. 77.5% of the indicated weight is 24-Karat gold, and will become 22-Karat gold after firing. Art Clay Gold Paste comes in two bottles. One has 1.5gm of thick paste; the other contains a 5ml medium that is used to dilute the paste to a more workable consistency on glazed surfaces.Fires at 800℃ / 1472˚F. The holding time will vary depending on the combined material.
Art Clay Copper
Art Clay Copper is the newest product in our range and is a clay material that can be utilized to make a wide range of pieces such as jewelry, craft designs, and objects like sculptures and models.
Art Clay Copper can be fired in an electric kiln with or without using carbon, with the resulting fired piece being more than 99.5% pure Copper.
(The percentage of copper in Art ClayTM Copper still in the clay state is 90%.)
