Glauber's salt
The Columbia Encyclopedia, Sixth Edition | Date: 2008
Glauber's salt common name for sodium sulfate decahydrate, Na 2 SO 4 ·10H 2 O; it occurs as white or colorless monoclinic crystals. Upon exposure to fairly dry air it effloresces, forming powdery anhydrous sodium sulfate . Johann Glauber was the first to produce the salt (from Hungarian spring waters). The naturally occurring salt is called mirabilite. Glauber's salt is water soluble, has a salty, bitter taste, and is sometimes used in medicine as a mild laxative; it is also used in dyeing.
