Product Information

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

Contains:

Lead

May react with:

Selenium, Sulphur

Cold Characteristics: 

Surface colour variations common; some light dappling. Colour range from light pink to deeper shades of lavender pink. Slight mottling on back of sheet.

Working notes: 

Typically deepens in coloration on firing. Dark interface reaction possible with sulphur glasses (1137, 1437, 0137). 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) – 667

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.

Fine and Medium frits usually appear lighter than their fired colour, even when the glass is not a striker. Coarse frits less so.

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).
