US Patent No: 4372774
Thermal treatment of glass
Abstract
The thermal treatment of glass is effected by contacting the glass, when it is hot, with a gas-fluidized mixture of particulate materials, at least one of which is selected to have gas-generating properties when heated by the hot glass. The materials are mixed in selected pre-determined proportions which impart to the mixture a thermal capacity and flowability which are such that a required thermal treatment is achieved. The method is particularly suitable for the thermal toughening of glass sheets for vehicle windscreens.
