Alchemical symbol

Alchemical symbols, originally devised as part of alchemy, were used to denote some elements and some compounds 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 by Isaac Newton. This page therefore lists only the most common symbols.

This article contains Unicode alchemical symbols. Without proper rendering support, you may see question marks, boxes, or other symbols instead of alchemical symbols.
