Tanning Composition.

The Scientific American 17, 6.1.1855

In examining our list of claims last week, there is one for a new composition for tanning, which consists of the muriate of soda (common table salt,) alum (sulphate of alumina,) and sulphuric acid. Now it strikes us that if the sulphate of soda and alum alone were used, the same effect would be obtained; for the soda of the common salt will leave the chlorine and combine with the sulphuric acid, and thus form glauber salts, setting the chlorine gas free - the water taking up a little of it.
