Bismuth123 by Tobias on Instagram: "A Bismuth crystal is a rare moment where science decides to show off. As molten bismuth cools, it doesn’t form a dull metal chunk, it grows stepped geometric “hopper” shapes, like tiny metallic temples spiraling inward. Its vivid rainbow colors aren’t painted but created naturally by light interference on a thin oxide layer—just like the colors in soap bubbles or butterfly wings. In the end, a bismuth crystal is physics wearing a tuxedo: proof that even the la

Quantaflix  on Instagram: "Bismuth has a rhombohedral crystal structure that favors right-angled growth. When it cools from melt, the outer edges solidify first, leaving the inside molten. The molten core pushes outward, forming layered terraces. These terraces align at 90° angles, giving the square, stepped shapes. The rainbow colors come from a thin oxide layer causing light interference. These Bismuth crystals looks amazing."
