Abstract
This invention is directed to the production of frits useful in decorating glazes and enamels for glass, glass-ceramic, and ceramic food service ware which exhibit coefficients of thermal expansion (20.degree.-300.degree. C.) between about 50-110.times.10.sup.-7 /.degree.C., a viscosity suitable for firing at about 650.degree.-775.degree. C., good glass stability, high gloss, and excellent resistance to attack by acids and bases, especially detergents such as are used in commercial dishwashers. The frits consist essentially, expressed in weight percent on the oxide basis as calculated from the batch, of:
