Usage:

Sodium sulfate is used as a "fining agent", to help remove small air bubbles from molten glass.

It also fluxes the glass, and prevents scum formation of the glass melt during refining.
Anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions.

Sodium sulfate 98% is important in the manufacture of textiles, particularly in Japan, where it is the largest application.
