Abstract
A curved laminated glazing includes an outer sheet of a soda-lime-silica colored glass and an inner sheet of a chemically-toughened sodium aluminosilicate clear glass having a thickness e2 ranging from 0.4 to 1.1 mm, the outer and inner sheets being joined together by a lamination interlayer, the colored glass having a chemical composition comprising a weight content of total iron, expressed in the form Fe2O3, ranging from 0.6 to 2.2%, the glasses of the inner and outer sheets being selected so that 0≤T10in−T10out≤20° C., where T10in is the temperature T10 of the glass of the inner sheet and T10out is the temperature T10 of the glass of the outer sheet, the temperature T10 being the temperature at which the glass considered has a viscosity of 1010 dPa·s.
