Bullseye stringers truly expand your creative range. You can use them straight out of the tube or shape them with a flame. Offsets, accents, displacements, the possibilities are endless.
A great medium blue on it's own, the options the metallic finish can offer will spark your creative juices.
Contains Copper, May React With Selenium, Sulfur.
Cold Characteristics
Consistent color.
Working Notes
At tack fusing temperatures, the surface frequently develops a metallic gray 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, 001437, 000137).
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 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, 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 300F/hr to 1525, with a hold of 1:00.
