Alchemical symbols were used to denote chemical elements and compounds, as well asalchemical apparatus and processes, until the 18th century. Although notation was partly standardized, style and symbol varied between alchemists. Lüdy-Tenger[1] published an inventory of 3,695 symbols and variants, and that was not exhaustive, omitting for example many of the symbols used byIsaac Newton. This page therefore lists only the most common symbols.
According toParacelsus (1493–1541), the three primes ortria prima – of which material substances are immediately composed – are:[2]
Western alchemy makes use of the four classical elements. The symbols used for these are:[3]

The sevenmetals known since Classical times in Europe were associated with the sevenclassical planets; this figured heavily in alchemical symbolism. The exact correlation varied over time, and in early centuries bronze orelectrum were sometimes found instead of mercury, or copper for Mars instead of iron; however, gold, silver, and lead had always been associated with the Sun, Moon, and Saturn.[note 1]The associations below are attested from the 7th century and had stabilized by the 15th. They started breaking down with the discovery of antimony, bismuth, and zinc in the 16th century. Alchemists would typically call the metals by their planetary names, e.g. "Saturn" for lead, "Mars" for iron; compounds of tin, iron, and silver continued to be called "jovial", "martial", and "lunar"; or "of Jupiter", "of Mars", and "of the moon", through the 17th century. The tradition remains today with the name of the element mercury, where chemists decided the planetary name was preferable to common names like "quicksilver", and in a few archaic terms such aslunar caustic (silver nitrate) andsaturnism (lead poisoning).[4][5]


The following symbols, among others, have been adopted into Unicode.

The alchemicalmagnum opus was sometimes expressed as a series of chemical operations. In cases where these numbered twelve, each could be assigned one of theZodiac signs as a form of cryptography. The following example can be found inPernety'sDictionnaire mytho-hermétique (1758):[8]
Several symbols indicate units of time.
The Alchemical Symbols block was added toUnicode in 2010 as part of Unicode 6.0.[9]

A list of symbols published in 1931:
An 1888 reproduction of a Venetian list of medieval Greek alchemical symbols from about the year 1100 but circulating since about 300 and attributed toZosimos of Panopolis. The list starts with 🜚 for gold and has early conventions that would later change: here ☿ is tin and ♃ electrum; ☾ is silver but ☽ is mercury. Many of the 'symbols' are simply abbreviations of the Greek word or phrase. View the files on Commons for the list of symbols.[citation needed]
