Process for manufacturing a glazing, and glazing thereby produced

A glazing comprises a glass substrate having an enamel layer adhered to at least a first surface portion, the enamel comprising 20 to 80 wt % frit and 10 to 50 wt % inorganic pigment. The thickness of the enamel layer is 2 m to 50 m, and the inorganic pigment has an infra-red reflectance such that the infra-red reflectance of the first portion of the glass substrate surface is 37% or higher over a region in the wavelength range 800 nm to 2250 nm. The glazing may be laminated, and may be a vehicle windscreen. A process for producing the glazing involves applying ink to a glass substrate, curing the ink thereby producing an enamel adhered to the glass substrate, and shaping the glass substrate by heating to a temperature above 570 C. The preferred inorganic pigments are of the Fe and/or Cr type in spinel, haematite or corundum crystal form.
