The determination of the origin of a bubble from its gaseous content is complicated by the interaction between the bubble and the melt. In order to study this interaction a molten soda-lime-silica glass has been bubbled with air, nitrogen, oxygen, carbon dioxide, argon and sulfur dioxide at 1470 deg C. The residual bubbles are characterized by a low pressure, heavy sulfur/sulfate deposits and very similar compositions (N2 and CO2). In particular, bubbling with oxygen produces bubbles with constant PN2 and PCO2 indicating that an equilibirum is reached.
