Black Opalescent Sheet Glass
Cold Characteristics
Although termed an opal due to its almost total lack of light transmission, this is (in terms of its composition) actually a transparent glass.
Working Notes
Double-Rolled & Single-Rolled Sheets
Most solid-color sheets are double-rolled. A few styles are also available in single-rolled sheets, and will have a smooth, undulating surface on the front, and orange-peel texture on the back side.
Single-rolled glass can produce dappled lighting effects that are highly valued in stained glass applications.
For Rainbow Iridescent Textures
Low viscosity. Will flow sooner and more than other glasses. In very thin sections the color may vary from reddish/gray to bluish/gray.

Lay-up: When Firing Rainbow Iridescent Texture sheet glasses face up on the top layer of a 6mm construction, some of the original texture often remains, even when firing to a full fuse (1490°F/810°C).
