ABSTRACT:
Glass-ceramic articles having compositional inhomogeneities are provided with uniformly colored gray stain decorations by heat treating a palladium-containing staining material prior to application onto glass-ceramic articles which have been crystallized by a separate heat treatment, and then subjecting the glass-ceramic articles in contact with the staining material to another heat treatment to produce the stain decorations.
