Abstract: The invention relates to a plate intended for covering or receiving induction heating elements, more particularly an induction cooking plate, said plate being a glass plate with a lithium aluminosilicate-type composition, said plate having a surface zone at least 5 ?m thick that comprises potassium ions in replacement of the lithium ions of the glass. The present invention likewise pertains to an induction cooking appliance incorporating said plate and to a method for producing said plate.

Abstract: A laminated glazing includes at least one outer glass sheet and a polymeric sheet, in which the outer glass sheet has a thickness of not more than 2 mm and a coefficient of thermal expansion of less than 70×10?7 K?1.

Abstract: A laminated glazing includes at least one outer glass sheet, an inner glass sheet and a polymeric insert located between the two glass sheets, in which the inner sheet has a thickness of not more than 1.5 mm, the outer glass sheet is a glass sheet of different chemical composition from that of the inner sheet, the difference between the temperatures Tp1 and Tp2 being less than 80° C., the temperature Tp1 being defined as the mean between the upper annealing temperature and the softening point of the outer glass sheet and the temperature Tp2 being defined as the mean between the upper annealing temperature and the softening point of the inner glass sheet.
