This Bullseye fusible glass sheet is hand rolled and compatible with all other Bullseye 90coe glass.
The picture shows what you can expect from your Bullseye sheet glass colours before and after heatwork in the kiln. Please note colour shades may vary depending on your web browser.
The top row shows the unfired cold glass colour. For stained glass, refer to the top row.
The same glass after firing to a full fuse is shown directly below the cold glass. For kilnformed glass, refer to the bottom row.
Cold characteristics - Deep Royal Blue colour. Striker
Fires to a consistent, transparent violet. The glass can become slightly cloudy with excessive heatwork.
Contains Lead. May react with glasses containing Selenium or Sulfur.
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.
