Notes
Used in cobalt sulfate stains. Also a major constituent of Egyptian paste.
The decomposition occurs in two stages: starting at 70°C it gradually decomposes into sodium carbonate, then around 1000°C it disassociates into Na2O and CO2.
This material can also be used to precipitate soluble salts in clays, in a manner similar to barium carbonate. Around 0.3% was needed in one plant.
