Title: Removing unwanted portions from hollow glassware - by applying line of conducting material and heating by electric resistance or induction to cause local thermal shock and fracture
Inventor: ILK EMIL
IPC: C03B33/095
Filed: 1978-04-14
Abstract: The zone of the glass object which is to be treated is coated with a substance (I) which absorbs energy from electromagnetic waves; induction or the direct use of energy is then employed to heat (I) and thus cause the desired transformation in the glass underneath the local coating (I). The pref. process consists of making a continuous or closed line of conducting material (I) on the glassware where fracture is to occur. Induction heating of the line (I) is then used to cause local heating and fracture of the glass along a desired path matching line (I). The induction heating may also be used to melt the cut edge of the glass to form a smooth surface. (I) is esp. a metal, e.g. solder tin, Ag, Hg, Bi, or mixts. of these metals. Used to eliminate the mechanical scoring of glassware employed to remove unwanted zones. A smooth fracture is obtd. so no subsequent grinding is required.
