Abstract: A process for obtaining a decorative mirror includes reflective regions forming a pattern and non-reflective regions, the process including providing a sheet of soda-lime-silica glass coated with a reflective coating on the entirety of one of the faces thereof, then applying a composition including a phosphate salt to the reflective coating, solely in application regions, the application regions being intended to become the non-reflective regions, then tempering the glass sheet, in which the glass sheet is subjected to a temperature of at least 550° C., causing the reflective coating to dissolve in the application regions so as to form the non-reflective regions in which the glass sheet is not coated.
