Summary

A problem with the process of applying porcelain enamel to steel range grates is described. Defects in the form of pinholes and black specks were observed frequently in a liquid porcelain coating line by one manufacturer of gas ranges. The chemical supplier, coating supplier, and range manufacturer developed a joint investigation to eliminate these problems. Processing of steel grates and the nature of the problems are described. Findings from the study are summarized and discussed in terms of recommendations to mitigate the occurrence of defects.
