BE - 0100 Black Opal Ribbon
Although termed an opal due to its almost total lack of light transmission, this is (in terms of its composition) actually a transparent glass.
Low viscosity. Will flow sooner and more than other glasses. In very thin sections the color may vary from reddish/gray to bluish/gray.
Fusible / Bullseye-compatible.
Ribbons are approximately 17.75" (451 mm) long, 4-5mm wide, and fettuccine-flat. Each ribbon expresses its handmade origins through slight organic variations in width and straightness. They are packed in clear plastic tubes that are 18" (457 mm) long and 0.75" (19 mm) in diameter, with approximately 32 pieces per tube.
