A method for producing a reflector on a reflector base made of glass is provided. According to the method, a metal-containing coating fluid is deposited on a coating surface and subjected to a burning-in treatment at a temperature below a softening temperature of the glass forming the reflector layer. Deposition of the coating fluid proceeds using a contactless method by inkjet technology. This makes it possible to deposit a reflector layer in a reproducible way and with tight tolerances having a specified layer thickness, as well as to create clean edges without a printing block or similar device. The coating fluid is moved by a print head equipped with a plurality of nozzles and is movable in a movement plane relative to the coating surface. The coating fluid is sprayed onto the coating surface by the print head under pressure and in the form of droplets emerging from the nozzles.

An apparatus is provided for coating deposition, particularly by chemical vapour deposition, on three-dimensional glass articles such as bottles. The apparatus lends itself to incorporation in a plant for a continuous production process for glass containers.

A low-reflection coated glass sheet of the present invention includes a glass sheet and a low-reflection coating formed on at least a portion of a principal surface of the glass sheet. The low-reflection coating contains 60 mass % to 100 mass % of a silica material having a continuous structure. The low-reflection coated glass sheet of the present invention maintains a large transmittance gain even when scraping against foreign matters.
