- Plaster of Paris is a great material to use for basic sculptures and craft projects
- Easy to prepare and sets in a few minutes
This white plaster derived from calcium sulfate, and named after a large deposit found in Paris, France, is ideal for the craft industry. It will harden to a porous, fairly brittle substance when mixed with water, which can be poured into moulds, or manipulated with tools or sandpaper.
It only takes a few minutes to set and will dry to a very smooth finish, and is sensitive to the textures of the mould. Moulds (plastic) can be bought, or manufactured using Dala Modeling Clay or Casting Rubber. It cannot be poured into a mould made from plaster, as it would stick to itself, so a release agent like casting rubber should be used.
ALWAYS start with the water and then add the plaster. Work in a dust free environment.
