Abstract

Method of tempering electric insulators, made of glass and having ridges in the under surface in which after moulding, when the surface is released from contact with the mould, and when the temp. is low enough for the glass not to be deformed, local heating is applied by jets partic. the ridges and the jets are rotated about the axis of the insulator. The insulator is then rapidly cooled.
