Oxycombustion has now become a well referenced solution for many operations involving hot glass. Nevertheless, this is more true for glass polishing than for glass conditioning. It will be shown that oxy-gas edge melting and polishing produces very good results in terms of quality, flexibility and economics. Due to the specific characteristics of the oxy-gas flame, it is possible to create a very high temperature gradient near the surface of the article resulting in a superficial remelt of the glass, without any significant increase of glass temperature inside the article. This is only possible with oxy-gas flames, due to their specific radiative spectrum and their high temperature. Industrial applications of this process, including related equipment developed by Air Liquide, will be briefly described in this paper.
