Soda ash obtained from "Salsola soda", "Salsola kali," and from other saltwort and glasswort plants was a very important commodity until the early 1800s, after which plant sources were supplanted by synthetic soda ash produced using the Leblanc process.

Plant sources were a very important source of soda ash until the early 1800s, after which they were supplanted by synthetic soda ash produced using the Leblanc process.
