Reaction of soda–lime–silica glass melt with water vapour at melting temperatures

“…However, both the level and lamellas should be soon depleted of sulfate ions and the question of the subsequent controlling process arises. It is known that sulfates considerably decrease the surface tension of glasses [13] and assemble on melt and particle surfaces. A part of the sulfates can thus be transported by rising bubbles to the melt level where they react.…”
