1. A method for producing a glass substrate with an embossed surface finish comprising the following steps:
abrasion of the glass substrate by sandblasting on one of the faces thereof with sand having 26-46% SiO2, 0.5-1.5% CaO, 12.5-32.5% A10, 24-44% FeO, 5-10% MgO, and 0.5-1.5% MnO;
screen printing process on a surface of the face subjected to abrasion;
drying of the deposited injected ink, and
tempering process.
