Abstract
Abstract A vehicle window 100 comprises a glass sheet 101 bearing a coating 102. The coating 102 is a tin oxide coating located on an external face of the vehicle window, and has been polished after deposition. Such a coating can confer increased abrasion resistance, and facilitates removal of frozen condensation. The coating may be electrically conductive so that it reduces the emissivity of the coated face in respect of infra-red radiation having wavelengths greater than 3 micrometers. A method of manufacturing a transparent vehicle window is disclosed which comprises depositing a coating on a face of a piece of glass in sheet or ribbon form, the coating deposited being a tin oxide coating. After deposition the coating is subjected to a polishing treatment.
