U+1F75D "🝝" Alchemical Symbol for Stratum Super Stratum-2 is a rarely used glyph found within the Alchemical Symbols block, representing a specific layered or stacked substance in historical alchemical notation. It visually depicts two horizontal lines or strata, with the upper one labeled "super" and the lower one marked as "stratum" or layer, indicating a compound or mixture formed by superimposing two distinct materials. This symbol was employed by early chemists and alchemists to denote a preparation where one substance is carefully placed atop another, often to observe reactions, distillations, or transformations between the layers.
