Title:
METHOD FOR SUPPRESSING REBOILING OF GLASS
Document Type and Number:
Japanese Patent JPH06329422
Kind Code:
A
Abstract:
PURPOSE: To suppress the reboiling in remelting a cullet of a high-strength glass composition consisting essentially of MgO, Al2O3 and SiO2.
CONSTITUTION: An inert gas or a gaseous carbon dioxide atmosphere or both are used as a remelting atmosphere. Thereby, dissolved oxygen in a glass melt is diffused into the atmosphere in remelting a cullet and reduced. Thereby, the reboiling in subsequent contact with the surface of a remelting container can be reduced.
