The fining agents are substances with numerous effects on glass melting. The second part of our review summarizes both the benefits and disadvantages of fining agents used in the glass industry for the purpose of degassing glass melts and removing bubbles from molten glasses. Particular attention is paid to the usage of sodium sulphate and also to the chemical and physical factors connected with such phenomena as bubble nucleation and the foaming of glass melts.
