U+1F734 "🜴" Alchemical Symbol for Regulus-3 Unicode Character

U+1F734 "🜴" Alchemical Symbol for Regulus-3 is an obscure typographic mark from the Alchemical Symbols block, representing a specific term used in medieval and Renaissance alchemy. "Regulus" referred to a purified metallic substance, often antimony, and the number 3 likely denotes a particular stage or variant in the process of refining or the metal's properties, possibly indicating a third purification or a compound associated with the metallic star (the "little king"). This symbol, featuring a central vertical line flanked by two horizontal crossbars atop a small circle or dot, was used by alchemists to encode specialized knowledge about materials and transformations, and its inclusion in Unicode preserves these historical notations for digital documentation.
