Product Information

Bullseye opalescent sheet glass has an assertiveness and complexity of colour that isn’t matched anywhere. These sheets, when held to light, respond with a fascinating array of complementary hues - like an opal.

Working Notes

Cold characteristics: 

Consistent colour. 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 colour may vary from reddish/grey to


All our glass is COE90, Bullseye Glass compatible and suitable for applications such as glass fusing, glass casting and glass slumping (unless otherwise stated in the description).

I use black opal Bullseye, 10 times more than any other colour, mostly used with black backed dichroic using the black opal as a base. The only glass I use slightly more of is the clear Tekta, which I use to cap dichroic glass with.

You can use 2 layers of plain black to make earrings, or 3 layers for a pendant.

Handy to have for jewellery making and I use this as the base for most of my pendants.
