Abstract
A new lead-free glass flux suitable for the decoration of ceramic materials comprises SiO2, Al2O3, B2O3 and Li2O as essential components. The lead-free glass flux is a glass mixture in which a glass composition having a relatively low coefficient of thermal expansion and a glass composition having a relatively high coefficient of thermal expansion and a relatively high chemical resistance are mixed at an appropriate ratio.
