To Clarify Liquids
The following composition is said to bleach all
colored liquids, and to render bone-black perfectly unnecessary:
Albumen three hundred, Neutral Tartrate of Potash two, Alum five, Sal
Ammoniac seven hundred parts. The Albumen must of course not be
coagulated. The ingredients are first dissolved in a little water and
then added to the liquid to be clarified.
