The Neolithic people of the Precucuteni Culture were boiling the salt-laden spring water through the process of briquetage to extract the salt as far back as 6,050 BC, while an ancient salt-works operation has been discovered at the Poiana Slatinei archaeological site in Romania.

The harvest of salt from the surface of Xiechi Lake near Yuncheng in Shanxi, China dates back to at least 6,000 BC, making it one of the oldest verifiable salt-works.
