Caustic Soda Pearls

Caustic soda pearls (also known as sodium hydroxide, caustic soda, NaOH, sodium hydrate, or Sodagrain) are white spheres of caustic soda with a barely perceptible odour. They are soluble in water, with the liberation of heat, and are stable under normal conditions.

Caustic soda is a strong base and, as such, has many applications in industries all over the world, both now and in the past.
