An improved glass powder is composed of better quality glass (i.e. Spectrum Glass). This our second major glass powder tested in our lab. It has ok damp strength, good green strength, and OK behavior in the kiln cycle.
Spectrum Powdered Glass – 1000 units
Powdered Sugar ———– 90-100 units
Maltodextrin ————- 90-100 units
The Spectrum Glass is available in cullet form (pieces of broken glass) which then must be crushed/powdered to better than 400 mesh. We had Olympic Color Rod perform this task.
If you can’t find Maltodextrin, then use Benefiber (it is no longer maltodextrin but rather a wheat dextrin).
The resulting parts are opaque white.
