Working Notes

Bullseye 164 Egyptian Blue Opaque frit offers a strong, saturated blue with a slightly green-leaning undertone, suitable for a wide range of fused glass applications, delivering bold, even colour and excellent coverage in both graphic designs and textured surfaces. Medium grade frit is best for tack fusing, textural surfaces, organic effects, colour buildup. Medium grade frit provides strong colour with visible texture and good melt control.

This frit is produced from crushed, screened, and magnetically cleaned Bullseye-compatible sheet glass to ensure consistency and compatibility within the Bullseye COE 90 system.

Available sizes:
• 30 gram sample
• 200 gram jar
• 500 gram jar

Fusible / Bullseye-compatible (COE090)

Working Notes

Opalizes upon firing. It may contain thin threads of colour variation.

At tack fusing and slumping temperatures, the surface may develop a metallic grey 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). Learn more by reading: Special Effects: Steel Blue Opalescent.

At a full fuse, Egyptian Blue Opalescent has the potential to deposit trace amounts of copper on the surface of the kiln shelf. These deposits may react with sulfur-bearing glasses in subsequent firings. Processes that require greater heat work, 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 when ThinFire has been removed and a new ThinFire is applied. This type of contamination is impermanent and may be burned out/fired out throughout subsequent firings. A contaminated shelf can be fired with glasses—other than sulphur-bearing glasses—and no reaction will take place. In our studios, we've observed the greatest contamination in subsequent firings with sulphur-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 the glass cleaner before firing.
