ABSTRACT:
A process for enhancing the adhesion of coatings applied to the surfaces of glass-ceramic articles. The surface area to be coated is roughened before the article is completely cerammed. When the article is subjected to elevated temperatures for the purpose of converting the green glass to a glass-ceramic, flaws produced by the abrasion step are healed. The coating can be applied before or after the ceramming step.
