Violet Striker maintains some transparency when it matures to its target colour on firing. From the blue shade of its cold form, this colour fires to a strong violet, darker than the soft Light Violet Transparent.
This glass style requires a longer initial hold time during firing to reach the target colour - please see the working notes below.
May react with:
A deep royal blue colour.
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.
