Bullseye Alchemy Clear Transparent Silver to Gold Double Rolled 3 mm Glass (s)
Please note: As stated on the Bullseye website: Glass is hand rolled and cut sizes are approximate. If you need the exact size of 10" x 10" or 5" x 10" for a project, we suggest purchasing the next size up of glass. Please be aware that glass sizes may be slightly larger or smaller that the size you are ordering.
See our Bullseye Reactive Potential charts for more information
Unfired sheet has a faint blue tint.
Upon firing, silver foil turns a golden color wherever it is in contact with 1015 (Alchemy Clear). On the sample tile above, the left side illustrates silver foil after being fired uncapped on top of 1015. The sample’s right side illustrates silver foil after being fired between a layer of Clear (any style) and 1015, with 1015 as the cap. (Faint blue color may be evident in any fired work containing 1015.)
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).
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.
