A glass frit is prepared by heating an initial glass frit in the presence of a reducing agent so as to reduce metal moiety in the glass structure of the frit and then cooling the reaction mixture. Preferably, the frit prepared is used in a method of forming electrically conducting silver tracks on enamel on glass windows, by applying to window glass an enamel composition containing the frit and on top thereof a silver composition in the shape of the tracks and firing the compositions, such that on the firing the reduced metal moiety reduces silver ions migrating through the enamel composition from the silver composition to elemental silver and thereby prevents or impairs them from interacting with the glass to form visible tracks.

[ What is claimed is:] [1.] process for preparing a glass frit adapted to be applied to a glass member (c) and also adapted to have a metallic element (a) deposited thereon wherein, upon firing of said frit, together with said metallic element and said glass member, said frit prevents migration of metallic ions from (a) to (c), which process comprises heating an initial glass frit in the presence of a reducing agent so as to reduce at least one metal moiety ion in the glass structure of said frit and then cooling said frit for subsequent deposition on said glass member, and for receiving said metallic element thereon.
