PMC3 is the 3rd generation clay produced by Mitsubishi Materials. The PMC3 range has a shrinkage rate of approximate 12-15%. Once fired the PMC3 is denser than either PMC+ and PMC Standard making is harder wearing and is therefore recommended when making rings and other objects that need to be "hard wearing". The lower minimum firing temp and lower shrinkage rate enables it to be combined with fused glass pieces.
Minimum firing temperature is 600o C.
