摘要 |
A glass glazing is provided with a coating of a colored enamel composition along one or more edges. The enamel composition includes a vitreous matrix pigment and from 2 to 5% by weight of powdered tin dioxide which preferably is an additive during a comminution step. The vitreous matrix which represents at least 75% by weight of the enamel composition includes the following constituents SiO: 25-33 (% by weight) PbO: 47-65 B2O3: 3-7 Na2O: 1-4 K2O: 0-2 Li2O: 0-0.8 ZnO: 0.2-0.5 and provides a molar ratio of SiO2 to PbO between 1.6 and 2.7. The total content of the alkaline oxide are less than 5% by weight. The linear thermal expansion coefficient of the vitreous matrix is less than the glazing to be coated. |
