Plaster of Paris. Perfect for modelling.
Plaster of paris heats as it sets. It can be painted with acrylic or poster paint. It can also be lightly sanded when dry. Approximate mixing guide: 2 parts powder to 1 part water. Place powder into a clean container, make well in the powder and slowly pour in water. Stir gently to a creamy consistancy. Tap sides of container periodically to bring up air bubbles. Only mix quantities as needed to avoid wastage. Sets in 1 hour (times may vary) although items should be left to thoroughly dry for 1-2 days. For best results: water and equipment should be clean. Do not mix fresh plaster with older plaster. Safety: Control dust formation and ventilate work area.
