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.

At a full fuse, Steel 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.
