摘要：The invention relates to a method for refining a lithium alumino-silicate glass that can be converted into ceramic in a controlled manner and is free from arsenic oxide, antimony oxide and tin oxide, the method comprising adding at least 0.05 wt % of raw materials that can be vitrified and melting said materials at a temperature lower than 1750°C. The invention also relates to a glass ceramic obtained from said glass coloured mainly by vanadium oxide. Application mainly in the production of cooking plates and tools.
