An apparatus for partially fracturing a glass body along a score line to facilitate subsequent severance of the body along such score line by conventional top and bottom roller devices. The partial fracturing is effected by an apparatus having an impact element periodically engageable against the glass body on the glass surface opposite the surface on which the score line is inscribed.

Method of and apparatus for severing glass

Apparatus for the destructive testing of glass sheets. The sheets to be tested are subjected to a differential pressure condition by establishing a vacuum on one side thereof and lowering the pressure on such side until the glass deflects to its breaking point. The vacuum system includes a control circuit which enables lowering the pressure in a controlled linear manner with time. The apparatus is designed to permit selection of and testing of sheets substantially immediately after the capping operation.
