GLAUBER'S SALT, decahydrated sodium sulphate, Na 2 SO 4, 10H 2 O.
Glauber's salt readily forms supersaturated solutions, in which crystallization takes place suddenly when a crystal of the salt is thrown in; the same effect is obtained by exposure to the air or by touching the solution with a glass rod.
Sodium sulphate, Na2S04, known in the hydrated condition (with ioH 2 O) as Glauber's salt, is manufactured in large quantities for conversion into the carbonate or soda (see Alkali Manufacture).
(3) Sodii sulphas (Glauber's salt), with its sub-preparation sodii sulphas effervescens.
Thus he clearly described the preparation of hydrochloric acid by the action of oil of vitriol on common salt, the manifold virtues of sodium sulphate - sal mirabile, Glauber's salt - formed in the process being one of the chief themes of his Miraculum mundi; and he noticed that nitric acid was formed when nitre was substituted for the common salt.

Mirabilite, or Glauber's salt, is commercially valuable, occurring in such quantities in parts of the lake that one may wade knee-deep in it; it separates 1 Besides these islands there are a few small islands farther N., and W.
