Autoclave Crazing Resistance Tester for Glazed Sanitaryware

Pressure autoclave that subjects glazed ceramic sanitaryware to steam at 350 kPa to check glaze crazing resistance. Used by washbasin and WC manufacturers for batch qualification and glaze-body fit studies.

Specification

Test pieces are placed in a stainless steel autoclave and exposed to a saturated steam pressure of 350 kPa for the specified hours, then dyed and checked for crazing lines. The unit has a programmable controller and safety valves. It helps tune glaze recipes and firing cycles.
