1246-30 Copper blue transp.

Metal effect !! At low fusing and bending temperatures such as 690°C, a metallic gray film often forms on the surface. When fusing to a full fusing temperature or above, yellow residues can appear on the oven plate. Remove the residues before the next fire and replace the release agent or the release paper to avoid possible contamination during subsequent fires. It can be expected that glasses containing selenium and sulfur react with the contaminated release agent. Contains copper May react with selenium, sulfur, Reactive 0009, 1009, 1019
