A glass laminate is produced using infrared emitters to deliver thermal energy to an unbonded glass laminate assembly. Heat may be conducted to the glass laminate by at least one ceramic glass substrate that absorbs at least a portion of the infrared radiation from the emitters, thereby bonding the glass laminate assembly more quickly and efficiently than a conventional vacuum bag process.

A process for preparing a laminated glazing comprises providing a first glass sheet formed into a desired shape with a first thickness by a first procedure and providing a second glass sheet formed into a desired shape with a second thickness by a second procedure with an interlayer located therebetween, and laminating together the first and second glass sheets and the interlayer at a temperature and pressure sufficient to adhere the interlayer material to the glass sheets and in which the process further comprises applying a mould which is shaped substantially the same as the first glass sheet, against the second glass sheet, during laminating to adhere the interlayer material to the two glass sheets such that after lamination, the shape of the second glass sheet is substantially the same as the shape of the first glass sheet.
