Abstract

Compsns. have a fibre softening point of 535-609 deg.C and consist of 0-30 wt.% Al2O3, 16-32% B2O3, 11-40% SiO2, 4-12% Li2O, 0-18% ZrO2, 0-20% SnO2, 0-2% CeO2, 0-15% La2O3, 0-16% CaO, 0-13% SrO, 0-7% BaO, 0-3.5% BaO, 0-3.5% Na2O and 0-2.6% F; where total SnO2 + CaO= 2-23%, ZrO2 + La2O3 = 2-33%; ZrO2 + Al2O3= 0-26.5% and CaO + SrO + BaO= 0-19.25%. A coloured enamel for decorating glass, glass ceramic and ceramic ware comprises the frit as above and 4-15% low expansion filler or pigment, pref. beta eucryptite filler, based on the wt. of glass frit. Stress is reduced in a decorating compsn. for application to glass, glass ceramic or ceramics by incorporating 5-15% wt.% low expansion filler in a glass frit as above. The frit is free from toxic components, has sufficient alkali resistance and hardness to withstand exposure to dishwasher cycles over many years, is harder and more scratch resistant than many present compsns., is resistant to acid fruit juices, and may be fired to form a smooth shiny layer without pattern bleeding and remains free from cracks and after firing and during use.
