A semi-empirical model of the bubble growth and dissolution in glasses with a fining agent has been derived. This model applies the experimental data from bubble observation at melting and fining temperatures. The experimental data needed for the mod

A simple model of bubble behaviour in a melting space with a vertical circulation of the molten glass was derived. Subsequently, two cases were considered. The first case with a constant, radially independent value of the angular velocity of the glas
