Bullseye Alchemy Clear Silver to Bronze (style 001016) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming.
Cold characteristics Unfired sheet has a faint coral tint.
Working notes 001016 Alchemy Clear, Silver to Bronze is designed to react with silver foil when fired together to turn the silver a bronze color. Expect variation in fired results across production runs. Part of a series that includes Alchemy Clear, Silver to Gold (001015). Expect variations in effects to result from different sources and thicknesses of silver, glass production runs, and heatwork (including firing times, temperatures, and number of times fired). We have also observed inconsistency in bronze reaction color within the silver when scaled up in larger projects. For color development, we recommend a 1-hour soak at 1225°F in the pre-rapid heat section of a firing cycle.
Reactions This is a Bullseye Alchemy glass. It reacts with silver foil or wire to shift color, which is the effect it is made for.
Format and sizes Double-rolled sheet, 3mm standard thickness, with a rolled edge. Available in the sizes shown above.
Fusing and compatibility Tested compatible with other Bullseye glass. When you combine it with glass from other makers, matching COE alone does not guarantee compatibility, so fire a small test tile first.
