ABSTRACT:
The invention relates to the measurement of stresses in float glass. In a process, the stresses in the glass are continuously determined by scanning the glass over its entire width and simultaneously measuring the temperature of the glass at each location scanned. A measurement of double refraction representing stresses is combined with the temperature measurement to establish values of the permanent stresses in the glass. The invention includes apparatus for carrying out the process.
