Bullseye Black Opalescent Double Rolled Iridescent Silver

Please note: As stated on the Bullseye website:  Glass is hand rolled and cut sizes are approximate.  If you need the exact size of 10" x 10" or 5" x 10" for a project, we suggest purchasing the next size up of glass.  Please be aware that glass sizes may be slightly larger or smaller that the size you are ordering.  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 Low viscosity. Will flow sooner and more than other glasses. In very thin sections the color may vary from reddish/gray to bluish/gray.
