Silica brick after service in the crown of a glass tank were carefully examined for alteration. Test specimens were selected by color zones and other evidence of change. The results show appreciable absorption of soda, which lowers the refractoriness of the brick but also promotes growth of large crystals of tridymite or cristo balite. A tentative explanation of “rat‐holing” is given and a means of reducing the attack is suggested.
