This handy reference guide explains what you can expect from your 2007 Bullseye sheet glass colors before and after heatwork in the kiln. Click on the small style swatches to the left to get info on individual colors. Check back to explore additional styles as they are added.

TRANSPARENT NOTES For each style, the top row shows the double-rolled, unfired cold glass color. For stained glass, refer to the top row. The same glass after firing to a full fuse is shown directly below the cold glass. For kilnformed glass, refer to the bottom row. Swatches shown are about two inches wide. GlassTips describe ONLY the results of standard full fuse + slumping firings, i.e.: glass 6mm thick, 10" (25cm) square, fired to 1480°F (804°C), held for 10 minutes, then fired a second time to 1250°F (677°C) for 30 minutes. To best ensure success, test glasses before use under your specific firing conditions. Use GlassTips information as a starting point only. Glass reactivity: Not all reactions are visible. Some are too weak to be seen and others are masked by dark color. "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. |
