  • Patent number: 5415731
    Abstract: A method of preparing a non-glare glass comprising (a) applying a printing ink consisting of water, sugar, carboxymethyl cellulose, starch powder, and aluminum oxide on the surface of the glass by means of a conventional screen printing technique; (b) dipping the glass into a dipping solution consisting of water, sugar, ammonium bifluoride, and ferric chloride; and (c) washing the glass thus treated with water. The resulting glass has a number of fine, transparent, etched patterns on its surface, and thus, can scatter light applied to the surface in a random manner, resulting in a non-glare surface. The process produces a glass having a non-glare surface, on which various and exquisite patterns are etched, without causing environmental pollution or injury to workers.
