FAQ
Frequently Asked Questions
Natural bismuth was long considered the heaviest stable element, but it is now known to be weakly radioactive with an extremely long half-life (over a billion times the age of the universe). For all practical purposes, it is treated as stable and non-hazardous from a radioactivity standpoint.
Bismuth subsalicylate has mild anti-inflammatory and antibacterial properties. It coats the stomach and intestinal lining, providing relief from discomfort, diarrhea, and indigestion.
In its pure form, it is a brittle, silvery-white metal with a pinkish tinge. When melted and slowly cooled, it can form spectacular, colourful, stair-step crystals due to oxide film interference on the surface.
It is about as abundant as silver in the Earth's crust but is rarely found in pure form. It is typically a byproduct of refining lead, copper, tin, and other ores.
