The present invention provides a method and apparatus for glass material or other similar material by vacuum. The clarification of the material to be melted, then the molten material into the vacuum chamber, it is best to introduce liquid above the chamber space. Other aspects include two steps ahead. To clarify the vacuum melting process in these processes. In the first phase, the material of liquefaction, basically completed particles dissolved in second stages. The best thawing material into the vacuum chamber immediately foaming.
