U+1F732 "🜲" Alchemical Symbol for Regulus Unicode Character
U+1F732 "🜲" Alchemical Symbol for Regulus is a glyph from the Alchemical Symbols block, representing the metallic substance known as regulus, which in early chemistry and alchemy referred to the pure, refined form of a metal, most famously antimony or arsenic, often obtained by smelting and separating it from its ore. The symbol itself combines a downward-pointing arrow with a small crossbar, likely derived from earlier alchemical notation to denote a concentrated or essential metallic principle. Historically, the term "regulus" (Latin for "little king") was used to describe the purified metallic core, and this symbol appears in manuscripts and printed texts from the 16th to 18th centuries, playing a role in the development of early chemical nomenclature and laboratory practices.
