An equipment for standardized casting of Co-Cr alloys in dentistry.

The temperature and the chemical character of an acetylene-oxygen flame change with change in the gasmixture. When heating a Co-Cr alloy with this flame both temperature and chemical character in the parts of the flame used may influence the temperature increase of the alloy. To study the influence of different acetylene-oxygen flames on the heating process of dental Co-Cr alloy, a gasmeasuring and casting equipment was constructed. This made it possible to cast in a standardized way.
