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



May react with:

Selenium, Sulphur

Cold characteristics:  

A deep royal blue with variations in colour density and transparency that can give it a mottled appearance.

Working notes: 

Matures to purple upon firing, often with mottles and streaks remaining. Additionally, this style often fires with blue hues and is not uniform in colour.

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've tried full fusing this glass in a Firebox 14 kiln at the recommended top temperature of 790°C for 10 minutes and it always comes out so dark that it looks black unless strong light is shining through it.
Does anyone know what I am doing wrong?
WARM GLASS REPLY: This is naturally a very dark glass, especially if layered up to 6mm, which shows its rich purple when backlit. Try layering with clear instead, or for a lighter purple glass try Violet Striker 1234.30
