Factors that contribute to the occurrence offishscale on porcelain enameled ware are identified. These factors can be broken down into three main categories, which form a process window: steel substrate, enamel coating, and shop process. By firing, in adverse conditions, samples of a steel that possessed an increased susceptibility to fishscaling, it was determined that increasing furnace moisture levels, lowering base coating weights, and increasing firing temperature (over-firing) all lead to an increase in the occurrence of fishscale.
