Effects Of Major And Some Minor Constituents On Glassmelting

The effects of the major and some minor constituents on the melting and fining characteristics of amber and flint container glasses are discussed. The constituents investigated were silica, alumina, lime, magnesia, soda, fluorine, barium oxide and sulfates. The effects were measured by seed count, visual analysis and low-temperature viscosity. Curves of fining time and low-temperature viscosity characteristics are presented.
