Clear, Silver to Gold 2mm Opal

Reacts With Silver Cold Characteristics Unfired sheet has a faint blue tint. Working Notes Upon firing, silver foil turns gold where it is in contact with the glass. Samples tile above illustrates firing silver foil uncapped on top of 1015 (left), and fired between Clear and 1015 layers with 1015 as the cap (right). Faint blue color may be evident in fired works. Note: When firing silver foil in the kiln, be aware that the silver reaction can travel across the glass surface and onto the kiln shelf, potentially affecting silver-sensitive glasses in one or more subsequent firings. This can happen even when new shelf release (paper or primer) is applied to the kiln shelf. When fired between layers, silver is generally more contained and less likely to affect the firing surface.
