3mm thickness.
Priced and sold per 10" x 17" piece. (+/- 1/2")

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-colour 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 colour may vary from reddish/gray to bluish/gray.
