Art Clay Silver 650/1200 Overlay Silver Paste (OSP) is "low-fire" silver clay in paste form, formulated specifically to use on glazed porcelain. Overlay Silver Paste is in a viscous, liquid form and water soluble, so that you can express 3 dimensional drawings on a surface of porcelain, ceramic or glass. After firing at appropriate temperature ranging from 650 C/1200F to 800C/1472F, it will turn into 99.9% silver. During firing, the pure silver powder solidifies. The binding agent consists of carbon, hydrogen and oxygen resulting in the release of harmless carbon dioxide and steam during firing. [Instructions] Some silver settling may occur at bottom of the jar. Stir the paste well with a brush or metal spatula before use. This product is water-based and can dry. Always keep the container tightly capped. If it dries, add a small amount of water to re-hydrate. To dilute the paste, take out the necessary amount and place it in a separate container. Then, add water a drop at a time. Do not dilute it directly in the bottle. It is important that your kiln's pyrometer is functioning properly. Always be sure to ventilate the workroom when using a kiln.
