Tile Thermal Shock and Crazing Resistance Autoclave

Pressure autoclave that exposes glazed tiles to steam at up to 5 bar and 150 deg C to reveal glaze crazing after dye inspection. Used by glazed tile manufacturers to verify body and glaze fit.

Specification

Tiles are heated to 150 deg C in steam at 500 kPa for 2 hours, and then examined with dye. Crazing of the glaze shows poor body and glaze fit.
