Art Clay Silver Overlay Paste is an Art Clay exclusive product.             Video

Especially formulated for use on glass, porcelain and glazed ceramics.

Simply paint your design on in a thin layer with a brush, dry, and fire. You now have a real pure silver decoration on your glass or ceramic project.

Create sgraffito designs, where you paint on a thin layer, leave it to dry, and then carve designs into the un fired silver so the porcelain shines through.

Art Clay Silver Overlay Paste is also ideal on glazed porcelain blanks.

The Overlay Paste can also be used for repairs and bonding silver clay pieces together and is a good alternative to the original but now discontinued Art Clay Oil Paste.

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 fibre. During firing, the pure silver particles solidify.

The special formula of this product ensures it can be combined with glass, porcelain and ceramic materials.

Some silver settling may occur at the bottom of the jar. Always 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, add a few drops of water and stir to combine.

This product is water-based and can dry up. Always keep the container tightly capped. If Art Clay Silver Overlay Paste becomes too thick, add a few drops of water and stir well.

Art Clay Silver Overlay Paste must be fully dried before firing.

FIRING INSTRUCTIONS

To fire, place the fully dried piece into 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 ceramic piece, you may want to slow down the *ramp speed (*how fast your kiln heats).

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 recommended by the manufacturer. 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.
