High-quality hard plaster for making bases of working models in the laboratory. Gypsum is not thixotropic and, due to its low expansion and viscosity, it is ideal for making bases of working models, as it fills the narrow spaces between the pins with just a little vibration, and the low expansion prevents deformation of the working model.
