Abstract
A method for spray-decorating a low-expansion glass, glass-ceramic or ceramic article having an expansion coefficient in the range of about 0-35.times.10.sup.-7 /.degree.C. with a relatively high expansion fritted ceramic enameling composition having an expansion coefficient in the range of about 45-75.times.10.sup.-7 /.degree.C. wherein good surface coverage and color uniformity in combination with acceptable spall resistance in the applied enamel are provided by applying the enameling composition as a very thin film in the form of a non-aqueous oil-based spraying suspension.
