Bullseye - COE 90
|Contains: ||Selenium |
|May react with: ||Copper |
|Cold characteristics: ||Pale transparent amber. Striker. |
|Torch: ||Strikes to a deep red in the flame and is rust colored in small amounts. Keep transparent by using it in small amounts with minimal heatwork, or adding it near the end of the time in the flame. Before it is put into an annealing kiln, check that it has truly struck; it should appear very dark, almost black. If it is still light in color, gently cool and reheat the glass without bringing it to a molten state and watch for the glass to darken as it strikes. Labeling is advised because rod looks very similar to 1137. |
|Kiln: ||Hue and saturation may differ slightly when compared to sheet glass; a wider range is accepted due to changes that occur in the forming process.|
"Striking glasses" change dramatically to reach target color during firing.Colors may vary, depending on firing schedule, rate, atmosphere, and heatwork. For color-sensitive projects, test before use.
