Caustic-Soda Process.

Description

Patent for mixing anhydrous sodium-sulfate with saw dust, heating the mixture in a furnace to 880 degrees Celsius and letting it partially cool. This process will convert the sodium-sulfate to sodium sulfide which when combined with the saw dust creates a liquid which will not oxidize because of the saw dust. The saw dust prevents the mixture from becoming volatile. When lime is added to the mixture then caustic soda is created.
