Measurement of the oxygen activity of tin used in the float glass forming process is crucial in determining the source of glass surface degradation. High oxygen content of the tin can result in tin surface bloom, glass staining and solar-control coating quality problems, as well as tin pick-up and cassiterite defects. If the operator knows the oxygen concentration of the tin, he can determine the optimum hydrogen concentration needed in various portions of the float bath.
