Also called caustic soda.
This is a powerful deflocculant in clay slurries and casting slips and behaves in a manner silimar to soda ash. However, it is corrosive and thus seldom used commercially.
Some people also use this for its chemistry to source Na2O to the glaze (it does not form crystals like soda ash). During the firing NaOH picks up oxygen and becomes Na2O.H2O. Thus we can deem Na2O.H2O as entering the kiln (weighing 80) and exiting as Na2O (weighing 62).
