Abstract

1,185,899. Moulding plastic substances. C. A. CHEESEBOROUGH. 11 Oct., 1968 [11 Oct., 1967], No. 46506/67. Heading B5A. [Also in Division C7] A method of removing a platinum foil matrix from a porcelain ceramic article formed thereon, e.g. a crown for a tooth, after the article has been fired, consists in forming bubbles of gas between the matrix and the adjacent surface of the article in order to reduce the adhesion therebetween and thereby facilitate the removal of the matrix. The bubbles may be formed by submitting the article to a process of electrolysis in which it forms an anode or cathode in an electrolytic solution e.g. of sodium chloride, and current is caused to flow between it and a cathode or anode. The latter may be of platinum.
