Description: Potassium Sodium Tartrate, Tetrahydrate, Granular, USP is sometimes referred to as Rochelle or Seignette's salt and used as a laxative. Rochelle salt or potassium sodium tartrate is an interesting chemical that is used to grow large single crystals, which are attractive and interesting, but also may be used as transducers in microphones and gramophone pickups. Potassium sodium tartrate is a double salt first prepared (in about 1675) by an apothecary, Pierre Seignette, of La Rochelle, France. is to leave the solution on the stove on the lowest setting while
