Crushed hard-fired clay, a source of grit for clay bodies.
Graded in size from 15 mesh (very course) to 150 mesh (extra fine).
Does not shrink in firing, so medium to course grades will show texture through thin to medium glaze.
Added to clay bodies to reduce shrinkage and give structure for throwing or hand building.

General purpose, quick setting gypsum based plaster for use in moulding.
Time to Set 5 - 10 mins.
Mixing Instructions:
(1) Ensure mixing equipment and water are clean. Water temperature between approx 15-20C.
(2) Approx 1.3 to 1.4 litres of water to 2kg of powder.
(3) Add plaster to water and leave to soak for approx 2 mins.
(4) Mix to desired consistency. Try and avoid air bubbles during mixing.
Casting:
(1) Shape the mould using suitable material.
(2) Coat the mould with a mould release agent.
(3) Pour the mixed plaster into the mould with tapping or vibration to minimise any air bubbles.
(4) Allow the plaster to set.
Mould Release Agents:
Porous mould materials require release agents to prevent adhesion of the plaster to the mould.
Typically these may comprise of two coats of a petroleum jelly, Stearic acid (1 part) /kerosene (2 part) mixture, special ‘soaps’ or quick drying lacquers
.
