The designation 'Plus' refers to the particle size, it is a finer grained version zirconium silicate (see notes Zircopax). Formerly known as Superpax.

My first zircopax kiln shelf passed with flying colors

My first zircopax kiln shelf passed with flying colors

It is 5 mm thick (compared to the 17mm of the cordierite one). It weighs 650 grams (vs. 1700 grams). It will perform at any temperature that any kiln that I have will generate and far in excess of that. It is made from a plastic body having the recipe 80% Zircopax Plus, 16.5% 60-80 Molochite grog and 3.5% Veegum T. The body is plastic and easy to roll and had 4.2% drying shrinkage at 15.3% water. The shelf warped slightly during drying, so care is needed. First-firing at cone 4 yielded a firing shrinkage of 1%). Notice that cone on the shelf: It is not stuck so no kiln wash is needed! Zircopax is super refractory! It is held together by sinter bonding, so the higher the temperature you can fire to the stronger it will be.

These bags actually contain Zircopax Plus since Trebol is the new owner of the company.
