Abstract
Abstract This invention relates to a method of decorating glass-ceramics by an ion-exchange staining method wherein a composition consisting essentially of silver salts, transition metal compounds, sulfur and bentonite is applied to the glass prior to ceramming, and the glass is subsequently decorated and converted to a glass-ceramic in a single heat treating operating involving a hold at temperatures of at least about 1,100*C.
