Kiln: 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.

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. This type of contamination is impermanent and may be burned out/fired out over the course of subsequen(more...)
