Art Clay Silver Paste Type consists of pure silver particles, a binding agent and water. The binding agent is produced from harmless pulp fiber. During firing, the pure silver particles solidify. The binding agent consists of carbon, hydrogen, and oxygen resulting in the release of harmless carbon dioxide and steam during firing. This product is low-fire clay that can be fired at 650ºC/1200ºF, and is pure silver (99.9%) after firing. The special formula of this product allows for combination with glass, porcelain and ceramic materials, and is also suitable for firing with sterling silver findings or wires (SV925 and higher quality recommended).
Note: Do not fire a soldered piece with 650/1200 Paste as the soldering temperature is lower than the firing temperature.
Some silver settling may occur at the bottom of the jar. Stir the paste well with a brush or a metal spatula before use. To dilute the paste take out the necessary amount and place it in a different container. (Do not dilute directly in bottle.) This product is water-based and can dry up. Always keep the container tightly capped. (If it becomes too thick, add a little water and stir well) Wash the paste off your hands with water after use. The clay may crack during firing if it is not completely dry. Some kilns display a different temperature from the actual inside temperature. It is known that silver will melt at 961ºC/1763ºF. It is recommended that your kiln firing temperature does not exceed 900ºC/1652ºF. You may combine 650/1200 Paste with the original silver clay series (clay, paste and syringe types), but the firing conditions should be the same as the original clay series.
Note: Do not bend the fired piece with unreasonable pressure. Keep the clay indoors, out of direct sunlight, and do not store in a refrigerator. For best results use the clay as soon as possible after opening the package.
Preparation |
|
||||
Drying | |||||
The following is a list of recommended ways to completely dry the paste before firing. | |||||
Hair Dryer | At least 10-15 minutes with 1200 watt hair dryer at a distance within 5-10cm/3in. from the piece. | ||||
Food Dehydrator | At least 10 minutes at 60ºC/145ºF | ||||
Oven | At least 10 minutes at 180ºC/330ºF | ||||
Hot Plate | At least 10 minutes at 150ºC-180ºC/300ºF-330ºF | ||||
Electric Kiln | At least 10 minutes 150ºC/300ºF | ||||
Air Dry | At least 24 hours at room temperature. | ||||
Warning: Do not apply heat above 250ºC/480ºF or the binder will begin to burn away.
How to Check If the Piece is Completely Dry
|
|||||
Firing | |||||
To fire, place the piece in a cold or warm kiln (below 300ºC/570ºF). (It is safest to start with a cold kiln.) Take at least 15 minutes to reach firing temperature. You may use any of the four firing temperatures and hold times listed below. If you are combining with other materials (i.e. natural stones, glass), please check the appropriate firing temperature and hold time. | |||||
Schedule | 1 | 2 | 3 | 4 | |
Firing Temperature | 650ºC/1200ºF | 700ºC/1290ºF | 750ºC/1380ºF | 780ºC/1435ºF and higher | |
Holding Time | At least 30 min. | At least 15 min. | At least 10 min. | At least 5 min. | |
Note:
|
|||||
Finishing | The surface of the fired piece will be white and matte due to the crystallization of silver, but luster can be obtained by polishing. (i.e. Stainless Steel brush, burnisher, sandpaper, file, etc.) | ||||
Completing | The completed piece is pure silver (99.9%). |
