Product Description

15g Art Clay Silver Overlay Paste is an Art Clay exclusive product, especially formulated for use on glass, porcelain, and glazed ceramics.

Simply paint your design on in a thin layer with a brush, let dry, and fire. You now have a real pure silver decoration on your ceramic! Create sgraffito designs, where you paint on a thin layer, leave it to dry, and then carve designs into the unfired silver so the porcelain shines through. This silver paste is ideal to use with our porcelain blanks. The Overlay Paste can also be used for repairs and bonding silver clay pieces together, it is a good alternative to the now discontinued Art Clay Oil Paste.

MATERIAL: Art Clay Silver 650 Overlay Paste consists of pure silver particles, a special binding agent and water. The binding agent is produced from harmless pulp fiber. During firing, the pure silver particles solidify.

Please note: Some silver settling may occur at the bottom of the jar. Stir the paste well with a needle tool before use. To dilute the paste take out a small amount and place it in a different container. This product is water-based and can dry up. Always keep the container tightly capped. If it becomes too thick, just add a few drops of water and stir well.

FIRING INSTRUCTIONS (Must be fully dried before firing)To fire, place the fully dried piece in a cold kiln (never warmer than 250ºC). To avoid thermal shock which can crack your ceramic/porcelain, it's best to start with a cold kiln. You also need to leave your piece to cool down inside the closed kiln, until it reaches close to room temp.Depending on the size of the ceramics, you might want to slow down the ramp speed (how fast your kiln heats). You can use any of the four firing temperatures and hold times listed below - choose the appropriate firing temperature and hold time depending on the material you are combining the paste with.These timings are as recommended by the manufacturers. As always with fine silver clay and paste, the longer and hotter you can fire, the stronger your silver will be.

*IMPORTANT - Please only fire with a torch if the material you have combined with the Overlay Paste allows you to do so.
