METHOD OF INCREASING THE EFFECTIVENESS OF A FINING AGENT IN A GLASS MELT

摘要

The feedstock to form a glass melt is melted in the first temperature T ₁ in which time is a glass melt containing at least one refining agent. The resulting glass melt is then cooled to a temperature T ₂ lower than the second T _1, the oxygen-containing gas is introduced by foaming the cooled glass melt. Glass melt is then reheated to the first temperature of the higher third temperature T ₁ equal to or less than T _3.; Glass melts, fining agents, oxygen, air bubbles formed
