Plaster of paris workshop

Plaster-of-paris moulds

1. Mix some plaster-of-paris and cold water. The quantity should be 1:1, ie. 100g plaster-of-paris to 100ml water. Sprinkle the plaster-of-paris onto the water, then stir this mixture. Let it stand for 90 seconds. Stir the mixture to a creamy consistency.
2. Pour mixture into moulds. Tap the moulds gently to remove any air bubbles.
3. Let the moulds set for an hour.
4. Turn the moulds over and take the shapes out. Trim any edges off with a knife.
5. Decorate the shapes with acrylic paint and leave to dry.
