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 280mm x 190mm x 50mm or 2660cm3
The re-useable bucket contains a cup for a simple measurement of 2 cups of plaster to 1 cups of water.
Wear an FFP3 dust mask when mixing powders.
Plaster contains <1% crystalline silica which if inhaled will cause long term lung damage, therefore we recommend the wearing of a P3 Mask. Keep working areas free of dust cleaning up with a damp sponge.
In keeping with our overall general advice, we also suggest wearing full PPE mask, safety glasses, gloves in a ventilated area.
It is a sensible precaution for children not to work with raw materials.

I like using Newcast plaster as it is really fine but has pretty good strength. There is a good choice of sizes and the tubs are great for storage and come in very useful after the plaster has been used. Good value
