  • Method of polishing the surface of glass articles
    Patent number: 4576571
    Abstract: A method of polishing the surface of a glass article consists in exposing the surface of the said article to a flame produced by oxygen and by a fuel. In order to obtain a perfect surface quality, whatever the thickness and configuration of the article processed, while preventing any premature collapse of the article in question, use is made of a flame such that the thermal energy originating from the transfer of heat by convection exceeds the thermal energy originating from the transfer of heat by radiation, and preferably of a flame of the oxygen-hydrogen type.
