Bismuth Heart

Listing is for a single heart made from Bismuth. Multiple pieces are shown in the stock photo to demonstrate variation in coloring and shape.

Bismuth is a fascinating element, known for its low toxicity and beautiful crystallization process. This metal is extracted from ores through a complex refining process. When molten bismuth cools and solidifies, it forms intricate stair-step crystals with a metallic sheen. The vivid colors are the result of a thin oxide layer that forms on the surface, reflecting light in a spectrum of colors. 

Creating a Bismuth Heart involves melting pure bismuth at temperatures exceeding 520°F (271°C). As the molten bismuth cools, it is carefully controlled to form the unique crystalline structures that give bismuth its signature geometric patterns and rainbow-like iridescence. This precise cooling process is what makes each Bismuth Heart a unique and scientifically fascinating piece of art.
