Principle:
Crazing means hair cracks on the glazed surface of the tile. The resistance to the formation of crazes is determined by subjecting whole tiles to steam at high pressure in an autoclave and then examining the tiles for crazes after applying a stain to the glazed faces. (Applying a coloring substance to the glazed surface)
