Copper Blue 001246-0030-F-1010

Reactive Potential

Contains: Copper (Cu)
May React With: Selenium (Se) / Sulfur (S), Reactive styles (000009, 001009, 001019)

Dark color reactions may occur at the interface with cadmium/selenium or sulfur glasses, and red-hued color reactions may appear with reactive glasses.

Copper Blue can leave a residue on shelf separators like ThinFire or primer when fired to a full fuse or higher. To prevent contamination in subsequent firings, thoroughly scrape and buff off the used primer before applying fresh primer, or replace used ThinFire with new sheets. Contamination effects are reactions that can occur when Selenium, Sulfur, and Reactive styles come into contact with copper-contaminated separators during firing.
