Red Transparent Dots COE90

Red Transparent dots do not look red in the bag. Out of the bag they are pale straw and amber yellow with some deeper gold slices. It is a striking color: the red develops in the kiln, not on the shelf.

Made from Bullseye glass, COE90, about 2 to 3 mm thick from 6 mm cane; use these with COE90 glass only. The red arrives in the kiln, so plan the piece around the fired color, not the bag. Over white or clear a tack fused dot becomes a ruby or a berry with depth; over black it settles toward a deep wine.

Why are they yellow, and will they really turn red?
This is a striking transparent. Unfired it reads pale yellow to amber; fired to fusing temperature it strikes to a clear red, and the shade depends on your schedule and how long it is held at heat. Over white or clear the struck red glows like a ruby; over black it darkens toward a deep wine. Tack fused on a light base it makes a convincing red gemstone or berry with depth.

Working Notes

Striking colors reward a test. Fire a few dots on scrap of your usual base with your standard schedule and note how deep the red comes in; a longer hold at process temperature generally strikes it further.
