Abstract
The present invention relates to a particle mixture comprising particles of glass frit and particles of a crystalline oxide material, wherein the glass frit comprises silicon oxide (SiO2), zinc oxide (ZnO) and sulfur (S) and wherein the D90 particle size of the particle mixture is less than 5 microns. The particle mixture may be used to apply an enamel to a substrate. The present invention further relates to the use of the particle mixture to form an enamel on a substrate, to a glass sheet and to an automotive window pane.
