Manufacturing process
Chemicals

Manufacturing process

Manufacturing of the soda pearls is quite similar to the evaporation process of liquid caustic soda, except in the final stage, where, instead of scales, the melted soda is screened on a plate with multiple perforations, thus forming small liquid spheres that flow into the tower by gravity. While falling, the drops are crystalized by cooling, in their flow against the ambient air, thus forming the pearls.
