I posted some casting questions on a hot glass forum and a few people suggested i try investment plaster reinforced with fiberglass mesh as the mold material, has anyone on this forum tried casting blanks?.
I dont know about this plaster idea, the steward mirror lab uses aluminosilicate fiber,and some kind of hi temp glue for the joints.
