Bullseye Glass 0164-30F Egyptian Blue SQFT Listing

Egyptian Blue Opalescent

Double-rolled, 3 mm, Fusible

Cold Characteristics

Partly transparent.

Working Notes

Opalizes upon firing. May contain thin threads of color variation.

At tack fusing and slumping temperatures, the surface may develop a metallic gray film. This effect is inconsistent and usually disappears at full fuse temperatures. To localize the effect, which only occurs where Egyptian Blue is exposed, cap or layer with clear. Consider testing for each specific application. To achieve this effect more consistently, consider using Steel Blue Opalescent (000146). 

At a full fuse, Egyptian Blue Opalescent has the potential to deposit trace amounts of copper on the surface of the kilnshelf. These deposits may react with sulfur-bearing glasses in subsequent firings. Processes that require greater heatwork, such as pattern or flow bar techniques, can also lead to copper deposits. Such deposits may not be visible and can react even when the shelf has been properly scraped and reprimed or, alternatively, when used ThinFire has been removed and new ThinFire is applied. This type of contamination is impermanent and may be burned out/fired out over the course of subsequent firings. A contaminated shelf can be fired with glasses—other than sulfur-bearing glasses—and no reaction will take place. In our studios, we’ve observed the greatest contamination in subsequent firings with sulfur-bearing French Vanilla Opalescent (000137) and Spring Green Opalescent (000126). For a burnout firing, we recommend a rate of 300°F/hr to 1525, with a hold of 1:00.

Note About Glass Cleaner: The exposed surface of 000164 has greater sensitivity to glass cleaner. Traces of this liquid, which often fire cleanly, may be visible in fired works as a metallic sheen. The metallic sheen is prone to develop at tack fusing and slumping temperatures as described above. To prevent it, be sure to buff the glass with a towel to completely remove glass cleaner prior to firing.

Bullseye Compatible.

Fusible / Bullseye-compatible. Matching COEs does not ensure compatibility between glasses from Bullseye and another manufacturer. All compatible Bullseye glasses are tested compatible with other Bullseye compatible glass.
