Si02-polymorphs and physical properties of Indian super duty (S.D.) silica bricks used for five years in the melter crown of a 285/tpd soda-lime glass plant with three pass regenerators were examined in order to determine the effect of temperature on the wear mechanism. Bricks near the rat holes, formed along the joint planes and thermocouple block joints and those away from the holes recorded some differences, particularly in their cristobalite contents, demonstrating the effect of temperature on changes of the brick properties.
