摘要

Lead-free and cadmium-free glass for glazing, enameling and decorating glass or glass-ceramics has the following oxide composition (wt.%): 0-10 lithium+sodium+potassium, at least 0.1 magnesium+calcium+strontium and 65 silicon. An independent claim is also included for glazing, enameling and decorating glass or glass-ceramics by grinding glass as above to form a frit with an average particle size of up to 10 mu m, working the frit into a suitable consistency, optionally with additives, applying the product to a surface and firing it.
