In addition to the tin and other metals we supply, bismuth is a minor metal that is used often by our customers as a grain refiner and as an environmentally friendly replacement for lead. Bismuth is also a common ingredient in low-melt and fusible alloys.
Bismuth is a brittle metal with a white, silver-pink hue, often occurring in its native form, with an iridescent oxide tarnish showing many colors from yellow to blue. The variations in the thickness of the oxide layer that forms on the surface of the crystal causes different wavelengths of light to interfere upon reflection, thus displaying a rainbow of colors. When burned in oxygen, bismuth burns with a blue flame and its oxide forms yellow fumes. Its toxicity is much lower than that of its neighbors in the periodic table, such as lead, antimony, and polonium.
