Frangible articles, such as dishes and vessels and including drinking glasses are coated with a protective coating of plastic preferably high temperature plastic. The plastic may serve as a safety coating, to diminish handling breakage and to act as a safeguard and contain glass particles in the event of breakage. The coating may comprise a laminate of two or more coatings, a first inner coating to enhance adhesion of subsequent coatings to the glacis or other material of the vessel, and a protective, high temperature outer coating, resistant to washing in a washing machine. An intermediate, softer coating of polyethylene copolymer may serve to better retain the particles of glass parent material, in the event of breakage of the vessel. The outer protective coating may be of high temperature thermoplastic or of thermoset plastic, to withstand handling and wear, including the effects of hot water, encountered in a dishwasher, and the heat of its drying cycle. The plastic coatings are well suited to enhancement, as by the application of decoration, including colour by inclusion with the plastic, the use of irridescent or pearlescent additives, heat-reponsive colour-change materials and I/R responsive materials. Also printing and tactile enhancements are possible. The plastic coating system may be used with ceramics.
