The method of the high temperature observation with subsequent bubble analysis by mass spectrometry was used for the determination of physical constants of gases dissolved in glass melts. The procedure arises from the mathematical model of the bubble behaviour in glass melt, namely the bubble size and composition developments. These two time dependences were also experimentally measured and used for the acquisition of diffusion coefficients, physical solubilities and actual concentrations of CO₂, N₂ and Ar in the TV glass at temperatures 1300°C and 1400°C.
