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).

Black Opalescent Rod

Cold Characteristics

True black.

Working Notes

Torch: Black Opalescent Rod (000100-0576) remains black except in extremely thin applications, when it may become dark gray. It is a soft glass. Beware of heating the glass so much that it bleeds and webs out over other glasses‚ or use this quality as a design element. Consider using Stiff Black Opalescent (000101-0576) for a crisper appearance.

Kiln: Working properties and kilnformed characteristics are consistent with sheet glass. See sheet glass notes for this style.
