Formation And Behaviour Of Bubble Curtains In Glass Melts

It is widely assumed that bubbles form in melts when their composition and/or gas-dissolving capacity is changed by the dissolution of refractories or sand. This phenomenon is shown by photographs of dissolving sand. In experimental investigations, it was not possible to explain bubble curtains in the vicinity of refractory materials by changes in composition. Computer simulations show that such bubble curtains can be formed even at a relatively low extent of bubble growth in the glass melt.
