STANDARD THERMAL‐SHOCK TEST FOR PORCELAIN ENAMELED UTENSILS*

Abstract
The equipment and method used in testing porcelain enameled utensils for thermal‐shock resistance is described. Test results are given which show that increased enamel thickness and decreased metal thickness decrease the thermal‐shock resistance of enameled ware. The mechanics of thermal‐shock failures is discussed. This study is one of a series sponsored by the Enameled Utensil Manufacturers' Council.
