The process for transforming an industrial soda-lime-type base glass plate into a glazed material with antimicrobial properties and personalized color consists in an antimicrobial glazed material production process. Copper nanoparticles (NPCu) are added to said glass with the aim of directly altering cell protection against viruses and bacteria in order to destroy their genetic material. The antibacterial glass is specifically applied to the industrial sector of surfaces and covers that are usually used in hospital facilities, and covers for the handling of food and beverages, among other uses.
