List of alchemical substances


List of alchemical substances

Alchemical studies produced a number of substances, which were later classified as particular chemical compounds or mixtures of compounds.

Many of these terms were in common use into the 20th century.

* Massicot - lead monoxide.:* Litharge - lead monoxide, formed by fusing and powdering massicot.:* Minium/Red Lead - trilead tetroxide, formed by roasting litharge in air.:* Naples yellow/Cassel yellow - oxychloride of lead, formed by heating litharge with sal ammoniac.
* Mercurius praecipitatus - red mercuric oxide.
* Milk of Sulfur (lac sulphuris) - formed by adding an acid to thion hudor (lime sulfur).
* Mosaic Gold - stannic sulfide, formed by heating a mixture of tin filings, sulfur and sal-ammoniac.
* Natron - sodium carbonate.
* Nitrum Flammans - ammonium nitrate.
* Oil of Vitriol/Spirit of Vitriol - sulfuric acid, a weak version can be formed by heating green vitriol and blue vitriol.
* Orpiment - arsenic trisulfide, an ore of arsenic.
* Pearl white - bismuth nitrate.
* Philosophers' Wool/nix alba (white snow)/Zinc White - zinc oxide, formed by burning zinc in air, used as a pigment.
* Plumbago - a mineral; graphite, not discovered in pure form until 1564.
* Powder of Algaroth - antimonious oxychloride, formed by precipitation when a solution of butter of antimony and spirit of salt is poured into water.
