Abstract
An apparatus and method for tempering glass is described. Glass sheets are passed through a tempering furnace along a predetermined generally horizontal path. The temperature of the sheets is measured by a pivoting pyrometer above the sheets and the furnace is regulated to achieve a zero temperature profile across the plates.
