Abstract: Enamel is composed of oxide forms, applied on a metal substrate with a firing temperature range of 800-870°C. Vitreous enamel coatings play a very important role in the coating production process of steel in accordance with the technical and aesthetic properties. Surface quality of the enamel coating can be affected by various defects. In this study, most common enamel surface defects obtained during laboratory trials have been investigated and elimination actions have been discussed.
