METHOD FOR MARKING A GLASS-TYPE SUBSTRATE SURFACE, SUBSTRATE AND MARKING DEVICE THEREFOR

摘要

The invention concerns a method for marking a glass-type substrate surface characterized in that it includes a step of mechanically marking the substrate surface in viscous state of specific viscosity, by mechanical contact with a surface made of marking material, the decimal logarithm of the viscosity of the substrate defined in poise being selected higher between 4 and 11, one at least of the substrate or the marking surface being flat and mobile in translation, the relative speed between the marking material surface and the substrate surface being non-null. The invention also concerns a marking means and the marked substrate.
