The maximum operating pressure is determined by the configuration
(dimensions) and the combination of materials of construction of the
sight glass. If the pressure is exceeded concentric or net shaped cracks
will appear in the surface of the glass on the low pressure side. Further
increase will result in enlargement of the cracks, slivers of glass will
come away and finally the glass will fail
