Newcast Plaster

Newcast plaster is a hard and more durable plaster giving a longer mould life. Primarily used in the ceramic industry to produce working moulds for the slip casting of tableware. It can also be used to produce working moulds for jiggering in tableware. Ideally suited to press and push moulds especially if they are frequently used. It has a fine particle size, giving excellent surface smoothness, the plaster also has good absorption capabilities.

Mixing ratio is 100 plaster to 57 of water, so for the 2.5kg powder in the bucket you would add 1.4Ltrs of water and that would make a shape with a dimension of 28cm x 19cm x 5cm or 2660cm³

The re-useable bucket contains a cup for a simple measurement of 2 cups of plaster to 1 cups of water.
