Bullseye frit is made from crushed, screened and magnetically cleaned Bullseye compatible sheet glass. Frits are very versatile and can be used in Pate de verre and kilncasting, kilnforming, torchworking and blowing. The colour of the frit in its unfired and fired states may differ greatly.
Some gold-bearing striking glasses like this one should be fired with a 2 hour hold at 1225°F during the initial stages of the firing cycle. If fired without this hold 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.
This full fuse schedule effectively strikes these glasses:
Rate Temp Hold
* 1225 2.00
600 1490 0.10
9999 900 **
* The initial rate of heat is not a critical factor in successfully striking gold-bearing glasses. Choose an intial rate of heat appropriate to the scale and design of the project that you are firing.
** The remainder of the cycle depends on the thickness of the piece. Consult the Bullseye Annealing Chart.
For colour-sensitive projects we recommend testing the cycle you plan to use by fusing a small sample of a similar setup in the same kiln as the project to best predict the final colour results.
The frit is supplied in a clear grip seal bag.
