Abstract
In a method for producing a biocidal glass surface of a soda-lime glass, a glass surface of a soda-lime glass is indirectly or directly contacted with silver, silver salt, or silver ions and directly or indirectly heated using at least one laser beam of a laser such that an ion exchange of sodium ions from the soda-lime glass with silver ions of the silver ions or from the silver or the silver salt results and silver ions of the silver ions deposit in the region of the glass surface. Before being heated, the glass surface is coated with a transfer support including a layer of silver and a protective layer covering the silver layer, such that the protective layer directly contacts the glass surface, the glass surface then being heated using the laser. Also, a soda-lime glass having a biocidal glass surface is produced by the method.
