001016 Alchemy Clear, Silver to Bronze

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.

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.

001016-0031 Alchemy Clear, Silver to Bronze (rainbow iridescent) Because iridescent coating acts as a barrier, don’t expect much reaction when using silver directly against this coated glass. That said, the silver might still make contact with the glass through thinner sections of the iridescent coating. This may result in bronze effects caused by 1016’s silver reactivity, detailed above. Results vary widely, both in terms of the effect’s strength and color.
