This plaster is a mold material made as heat-resistant plaster for glass crafts. For pâte de verre (soda glass, lead glass). It has excellent heat resistance and is designed to prevent yellowing of lead glass. It is for glass crafts such as pâte de verre. Similar to general gypsum plaster casting, it can faithfully reverse the fine patterns of the model and obtain an extremely smooth surface. "High Stone C-2 Type G" is a non-foaming casting plaster that mainly contains α-type calcined gypsum and various refractories. It is a precision casting plaster with excellent heat resistance, suitable for casting non-ferrous metals and low-melting alloys at a casting temperature of 800°C or less. Similar to general gypsum plaster casting, it can faithfully reverse the fine patterns of the model and obtain an extremely smooth surface.
