Characteristics

This is specifically formulated to bond to non-porous or glazed surfaces such as porcelain. Its viscosity can be adjusted by water which increases the way of expression. It turns into 99% silver form after firing. The surface of the fired area where Overlay Silver Paste was applied will be white and matte due to crystallization of silver, but a luster can be obtained by polishing. (Stainless blush, burnisher, sandpaper, file) Some silver settling may occur at bottom of jar. Stir the paste well with a brush or spatula before use. This product is water based and can dry up. Always keep the container tightly capped. If the paste dried up, add a little water to recover its original state. To dilute the paste, take out the necessary amount and place it in a different container. Then, add necessary amount of water. *Do not dilute it directly in the bottle.
