Semi Hard White, Type 2 Plaster, Nature

The unique thing about the Semi Hard is that these alabaster plaster have a higher hardness than the Normal Hard White by adding hard gypsum. This gypsum is therefore specially designed for workpieces for which a hard stone is too hard and model plaster too soft. Use the Semi Hard for manufacturing individual impression trays and embedding prostheses. Suitable for the casting technique (advice: use for the press technique Extra Hard White)
