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



Reactive Potential:

 May react with
Selenium, Sulphur Cold Characteristics Consistent colour.

Working Notes:

This glass can be unstable when subjected to extended
heatwork (pattern bars, pot melts, boiled effect, kilncasting, etc.).

Firing above 1500°F (815°C) for more than 15 minutes or
firing slowly between 1250°F (677°C) and 1500°F (815°C) may result in an
unstable glass. More susceptible to contaminants that seed devitrification than
other glasses in the Bullseye line.

Cap with clear or plan to treat the surface (sandblast,
coldwork, or apply clear powder and refire) after firing. No colour shift upon
firing. A dark interface reaction is possible with sulphur-bearing glasses
(001137, 000137). Dense White Powder (000313-0008F) is recommended for surface
use only. It may crackle when used between sheet glass layers.

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).

When making jewellery, this white opal is very stiff. It is the only bullseye that I have found in either transparent or opal, that melts much more slowly than all the other bullseyes in either transparent, or opal, and I have tried a lot. This white always stays square and still has quite sharp corners, even when the topping transparent Bullseye has roundly melted. I have only bought this once and far prefer the other whites available in bullseye, which are far better for jewellery making and round off nicely.
