Abstract:
A glass making process comprising a step of fining the molten glass in a fining vessel comprising a top wall portion not in direct contact with the molten glass, and a side wall portion in direct contact with the molten glass, wherein the top wall portion has a temperature T(top), the side wall portion has a temperature T(side), and T(top)−T(side)≦10° C., and a glass fining system. The invention is particularly useful for glass fining systems comprising a metal fining vessel made of precious metals such as Pt and/or Pt—Rh alloys.
