I'm just now realizing by watching this that bismuth isn't iridescent. The colors look like iridescent tones, but they aren't changing as the angle changes, it's just colored that way.

pretty neat right? It's grain structure orientation related

Interesting! Source?

I was under the impression it was just thin film interference from varied thickness of the oxidation layers, depending on how quickly it cooled...

The source is physics and properties of materials 101, I'm not about to spend my time digging up old textbooks to cite you a reference, sorry, no disrespect intended.

Unfortunately it wont stay colored like that. It will eventually tarnish and turn a boring non-shiny greyish silver color.

That’s what happened to all my bismuths :c

I was just thinking about this. It wouldn’t tarnish if you encased it in resin, right?
