Cold Characteristics

A deep royal blue colour.

Working Notes

Colour usually deepens on firing. Possible dark interface reaction with selenium and/or sulphur glasses (000137, 001122, 001125, 000124, 000125, 001137, 001437). Less viscous (softer) than most other glasses. 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:

* 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.

** The remainder of the cycle depends on the thickness of the piece.
