Many more symbols were in at least sporadic use: one early 17th-century alchemical manuscript lists 22 symbols for mercury alone. [10] Planetary names and symbols for the metals – the seven planets and seven metals known since Classical times in Europe and the Mideast – was ubiquitous in alchemy.

Alchemical Symbols is a Unicode block containing symbols for chemicals and substances used in ancient and medieval alchemy texts. Many of the symbols are duplicates or redundant with previous characters. [3] Few fonts support more than a few characters in this block as of 2021. One that does and is free for personal use is Symbola 14.0.
