ABSTRACT:
In forming a laminated glass article a first stage comprises assembling two glass sheets with an interlayer of thermoplastic transparent plastics material and heating the assembly to a first temperature at which some softening of the plastics material occurs. In the second stage the assembly is heated to a second higher temperature and maintained at the second temperature for a period such that full bonding occurs between the glass sheets and the interlayer, and then cooled, the exposed periphery of the interlayer being maintained at a pressure which is a controlled amount below that applied to the faces of the glass sheets for at least part of the period that the assembly is heated to the second temperature.
