Sodium sulfate is as a filler in powdered home laundry detergents. Another major use for Na2SO4
is in the Kraft process for the manufacture of wood pulp. Organics present in the "black liquor" from
this process are burnt to produce heat, needed to drive the reduction of sodium sulfate to sodium
sulfide. The glass industry also provides another significant application for sodium sulfate. It 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. Sodium sulfate is important in the manufacture
of textiles. It helps in "levelling", reducing negative charges on fibres so that dyes can penetrate evenly.
Unlike the alternative sodium chloride, it does not corrode the stainless steel vessels used in dyeing.
Glauber's salt, the decahydrate, was formerly used as a laxative. It has also been proposed for heat
storage in passive solar heating systems. Other uses for sodium sulfate include frosting windows, in
carpet fresheners, starch manufacture and as an additive to cattle feed. In the laboratory, anhydrous
sodium sulfate is widely used as an inert drying agent for organic solutions; Na2SO4 is added to the
solution until the crystals no longer clump together.
