Our Pottery Plaster is fine grade plaster of Paris which is used for mould making and casting because it picks up fine detail.It is off-white in colour and has an approximate initial setting time of 30 minutes. It can be carved, turned or sanded when completely set and can be painted using acrylic paints.The plaster can be stored for up to 6 months providing that it is kept in a dry storage container and the lid is properly secured after use.InstructionsTo find the amount of plaster/water mixture needed for your cast, firstly fill the mould with clean water and pour it into a mixing bowl. Dry the mould prior to casting. On average ratios are 850g of plaster to 1 pint of water. Slowly pour plaster into the water and stop when the mound of plaster powder starts to show above the water. Mix gently, but quickly, until you have a smooth creamy consistency. Try not to whip/beat the mixture, as this will create air bubbles.Whatever type of mould you are using, firstly pour in a small amount
