PRODUCING TEXTURED FLAT GLASS BY FLOATING

摘要

The invention relates to a method for producing flat glass including a surface texture by floating a ribbon of said glass on molten metal (32) in a floating chamber including a printing cylinder (30) for applying a texture to the upper surface (31) of the glass, characterised in that the glass ribbon is cooled downstream from the printing cylinder (30) so that a temperature difference of at least 150°C is obtained at the glass surface between a point located at the glass surface 50 cm before contacting the cylinder (30) and a point located at the glass surface 50 cm after contacting the cylinder (30). The invention also relates to a glass sheet having an energy transmission higher than 85% for a glass thickness of 3.2 mm, including two main surfaces, i.e. a main surface with a raised texture and another main surface enriched with tin.
