To study the influence of fining temperature on glass qualities, different fining temperatures from 1400°C to 1500°C were used to prepare a series soda-lime-silica glass with identical chemical compositions. Infrared spectroscopy was used to determine the water content of glass, general analyzer of melt physical properties was used to study the viscosity and surface tension change of glass melt, microscope was carried out find glass bubbles, wet chemical analyses were used to determine the Fe2+/(Fe2++Fe3+) ratio. The results show that, generally, with the increase of fining temperature, the glass melt’s water content, bubbles number and Fe2+/(Fe2++Fe3+) ratio increase, viscosity decreases. Particularly, when the fining temperature is 1450°C, the glass has lowest water content, bubbles number, Fe2+/(Fe2++Fe3+) ratio, and viscosity, and its surface tension is largest. Among all tested fining temperature, 1450°C is the optimal fining temperature.
