Ruby Red Tint Striker Billet.
Fires to a beautiful rich ruby red tint. Each Bullseye billet is approximately 127 x 254 x 19mm and weighs about 1.5kg. The three stacked billets in the picture demonstrate the increase in colour saturation with thickness. In kiln casting, the form and particle size of the glass selected can strongly influence the appearance of the finished piece. For maximum clarity, the rule of thumb is to use the largest and thickest forms of glass. Smaller glass particles increase obscurity due to air trapped between the pieces.
May React With:
Appears close to clear with blue/green tints.
Colour usually deepens on firing. Possible dark interface reaction with selenium and/or sulphur glasses (0137, 1122, 1125,0124, 0125, 1137, 1437). Less viscous (softer) than most other glasses. Some gold-bearing striking glasses, like this one, should be fired with a 2 hour hold at 663°C 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 should effectively strike these glasses:
* The initial rate of heat is not a critical factor in successfully striking gold-bearing glasses. Choose an initial rate of heat appropriate to the scale and design of the project that you are firing.
** Remainder of 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 final colour results.
Please note the weights of the billets can vary quite a lot so we recommend that you over compensate if you need a specific weight.
All our glass is COE90, Bullseye Glass compatible and suitable for warm glass applications such as glass fusing, glass casting and glass slumping (unless otherwise stated in the description).
