Product Information

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

Bullseye frit is made from crushed, screened and magnetically cleaned Bullseye Compatible sheet glass. Available in a huge variety of colours, frit gives the opportunity to add a unique element to your glass work. Frits are extremely versatile and can be used in kilnforming, including glass sketch and painting with light techniques, as well as in torch working and blowing, to create colours and patterns on surfaces.

Frits are available in a Powder, Fine, Medium, Coarse and Extra Coarse form.

Working Notes

Note: 

Powder frits usually appear much lighter than their fired colour, even when the glass is not a striker.

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

Hold –
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).
