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.

Abstract: A material includes a glass sheet coated on at least part of one of its faces with a stack of thin layers, the stack being coated on at least part of its surface with an enamel layer including zinc and less than 5% by weight of bismuth oxide, the stack further including, in contact with the enamel layer, a layer, called contact layer, which is based on an oxide, the physical thickness of the contact layer being at least 5 nm.

Abstract: A glass substrate includes on a face a water-insoluble polymeric temporary protective layer intended to be removed by heat treatment during a processing operation, and an enamel layer that has a mixture of glass frit, inorganic pigments and organic components that is deposited on at least one portion of the protective layer. The enamel has a glass transition temperature Tg above the temperature Tc60%, defined as being the temperature at which 60% of the initial weight of the protective layer is consumed, a maximum shrinkage measured by thermomechanical analysis between 450° C. and 650° C. greater than 20%, a difference between the inflection point temperature Tinflection and the glass transition temperature Tg less than 60° C., the inflection point temperature being defined as being the temperature at which the rate of displacement measured by thermomechanical analysis of the enamel is maximum, and a content of inorganic pigments less than 35% by weight.
