This fine casting Brian Clegg Plaster of Paris is ideal for making small to large models either in batches or as one off fine art sculptures. Once completely set can be finely carved, turned or sanded. The finished work can then be painted and varnished. Brian Clegg Plaster of Paris can be poured in to moulds and does not crack like clay. Mix 100g of powder to 70g of water to obtain a good creamy consistency. The less water you use the quicker it sets. Setting time varies according to ambient temperature and amount of water added. Mixed to the recommended ratio and at room temperature it will set in approximately 20 minutes. To maximise shelf life store in a dry place and keep well sealed.
