CRYSTALLIZING ENAMEL COMPOSITION AND METHOD OF USING THE SAME |
摘要 |
The present invention provides a new and useful composition and method of using the same for producing an enamel finish on a formed section of glass. The composition partially crystallizes upon heating, thereby helping to prevent the forming and handling equipment from sticking and/or adhering to the composition during the forming operation. The composition includes a crystallizable glass frit and a seed powder. The crystallized glass frit includes precursors from which Zn2SiO4 can be crystallized upon firing of the composition. The seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a portion of the crystallizable glass frit yields crystallized Zn2SiO4 formed by the precursors. Preferably, the precursors comprise ZnO and SiO2, and the seed powder comprises crystalline Zn2SiO4.
