Casting Plaster - High Strength

Glass-Cast 400 is an economical casting plaster for the glass artist who struggles with mould integrity due to mould size or process intensity. It is less likely to cause veins or cracks during casting, which helps reduce coldworking required afterwards.

Use for kiln casting and glass slumping.

Makes a single-use plaster mould, for moulds suitable for multiple firings, try Castalot.
