These fractal patterns are known as hopper crystals, identifiable by their hollow step lattices. When bismuth cools it forms in a rhombohedral structure with the edges of the formation crystallizing at a much faster rate than the center of the faces. This pulls material away from the interior and leaves gaps in the structure, causing the final product to appear hollow. \u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" class=\"lazyload\" data-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0709\/1715\/files\/bismuth-crystal-pinch_1024x1024.jpg?v=1602707663\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAbove: Close-up of a specimen displaying the intricate lattice pattern.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe crystal’s uniquely iridescent shine also occurs during its formation process.

It is not well understood how bismuth subsalicylate operates when ingested, but it is thought that it stimulates the absorption of fluid and electrolytes within the intestine while inhibiting inflammations.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eLong thought to have been the heaviest nonradioactive element, researchers in 2003 discovered that the naturally occurring isotope of the bismuth did in fact undergo alpha decay and calculated a half-life of 1.9×10^19 years. Luckily, this half-life is about a billion times longer than the current age of the universe, meaning that you won’t have to worry about any radioactivity from Pepto-Bismol or this specimen. 😎\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFurther Reading:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAgricola, Georgius.
