Working Notes

May have dark color reaction at interface with cadmium/selenium or sulfur glasses. May have a red-hued color reaction with reactive glasses.

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.
