Does anybody have a recipe for the combination needed to mix silicate powder and casting plaster for mold making? Thank you.

Plaster of Paris (from Lowes)
Diatomateous Earth (swimming pool filter media from Walmart)

It may not be "the best" mix, but the only exotic stuff is the shelf wash, which you should already have.
This mix can be reused several times if kept below about 1450° F.
I've run over ten slumpson a single mold when bending stained glass panels for "Tiffany" replacements.
Does this mixture shrink when you use specifically for the replacement bent panel lamps? - Barbara
