This Bullseye fusible glass sheet is double rolled and compatible with all other Bullseye 90coe glass.
The picture shows what you can expect from your Bullseye sheet glass colours after heatwork in the kiln. Please note colour shades may vary depending on your web browser.
Cold characteristics - Uniform colour.
Contains Copper. May react with glasses containing Selenium, Sulfur and Reactive glass (0009, 1009, 1019).
Working Notes - May have a dark colour reaction at interface with cadmium/selenium or sulfur glasses. May have a red-hued colour reaction with reactive glasses.
Important - Copper Blue may deposit a residue onto shelf releases (ThinFire, primer) when firing to a full fuse or hotter. Scrape and thoroughly buff off used primer, then apply fresh primer; or remove used Thinfire and replace with new to avoid possible contamination effects in subsequent firings. These contamination effects are essentially reactions, possible when Selenium, Sulfur and Reactive styles are fired while in contact with a copper-contaminated separator.
Example of French Vanilla glass reaction resulting from contaminated separator (right side); the left side had primer thoroughly removed and new primer applied.
Bullseye glass is a handmade product and colours may vary slightly between production runs. Some colours may change slightly upon repeated firing or with extensive heatwork. It is recommended that you test glasses before use under your specific firing conditions.
