Bullseye 146 Steel Blue Opaque frit offers a cool, muted steel blue opaque tone with a smooth, solid surface and consistent coverage. 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.

Working Notes
At tack fusing temperatures, the surface frequently develops a metallic grey film. This usually disappears at full fusing temperatures. To maintain the metallic effect, fire as quickly and low as possible. Dark interface reaction likely with sulfur glasses (for example 001137,Ā 001437,Ā 000137).Ā
At a full fuse, Steel 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 a greater network, 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 glassesāother than sulphur-bearing glassesāand no reaction will take place. In our studios, we've observed the greatest contamination in subsequent firings with sulphur-bearingĀ French Vanilla Opalescent (000137)Ā andĀ Spring Green Opalescent (000126). For a burnout firing, we recommend a rate of 300Ā°F/hr to 1525, with a hold of 1:00.
