Abstract
A method for producing decorated glass-ceramic articles is disclosed. The method involves contacting a surface of a crystallizable glass with molten tin and thereafter applying to the tin-contacting surface a stain decorating composition. The article is then fired at a temperature such that the glass simultaneously crystallizes and the stain diffuses into the article to form the decoration.
