Extraction Of Oxygen During Heat Treatment Of Silicate Melts Under Vacuum Conditions

Degassing experiments showed that a remarkable volume of oxygen is evolved above 1100 degrees C by heating a silicate glass under vacuum. The degassing is discussed in terms of a "fining" behaviour which reflects the tendency of bubbles to nucleate in a melt under a particular set of conditions.
