How to Prevent Glass Separator from Sticking to the Glass
A coat of glass separator will usually last several firings. The lower the fusing temperature, the more firings you can get from one application of separator.
If the glass separator is sticking to the glass, fire to a lower temperature. Are you sure you need a "full fuse"? (This is where the surface of the fused piece is completely flat and the separate pieces of glass have merged together.) At lower fusing temperatures, very little glass separator sticks to the glass.
Whenever you notice the separator cracking or chipping on the shelf, apply a fresh coat. Remove most of the old separator from the shelf with grit cloth (available from Paragon). This is an abrasive-coated mesh that allows residue to pass through. Removing the old separator gives you a smooth surface to start with. Then recoat the shelf.
