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.

This glass style requires a longer initial hold time during firing to reach the target colour - please see the working notes below. 

Working Notes

Contains:

Lead

Reactive Potential:

May react with Selenium, Sulphur

Cold Characteristics:

This style may not reveal (or



strike to) its target colour until fired. Colour range from paler to deep

shades. Some variations from pink to brown tones. Slight mottling on back of



sheet.

Working Notes:

Generally, deepens in hue on firing.



Dark interface reaction possible with sulphur glasses (001137, 001437, 000137).



Mottling disappears on firing.

Some striking glasses like this one need to be fired
slowly during the initial stages of the firing cycle. If fired too fast
they may not strike at all or they may strike, but appear spotty and have a
blue-brown cast as opposed to the desired target colour.  A standard
full-fuse schedule should work to strike these glasses:

 Segment 1:

Rate
(°C/hr) – 222

Temp
(°C) – 677

Hold –
0:30

 Segment 2:

 Rate
(°C/hr) – 333

Temp
(°C) – 804

Hold –
0:10

 Segment 3:

 Rate
(°C/hr) – 999

Temp
(°C) – 482

Hold – 0:60

Segment
4:

 Rate
(°C/hr) – 83

Temp
(°C) – 371

end

For
projects that are especially colour-sensitive, we recommend fusing a small
sample, with a similar setup in the same kiln, to best predict final colour
results.

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).
