In an attempt to determine the volatile components in various industrial, laboratory and natural glasses, the gas release from the silicate melts in high vacuum - high temperature extraction experiments were analyzed by simultaneous TG and mass spectrometry. In the temperature range from 800 to 1200 o C molecular fragments with m/z=13, 15, 27, 28, 29, were detected, which are possible fragments...
