The Skeptics Guide #1084 - Apr 18 2026

Yeah, that's interesting.

Sandblasting.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

It's so interesting.

Silver is like, I mean, I guess it's not different.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

It's all the same principles, but like we anneal silver to make it more, I guess, ductile, more workable, but it's way softer.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

Yeah, exactly.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

And then when you hammer it, when you work with it, it becomes work-hardened and needs to be softened again.

Bronze, silver, any jewelry metal is like that.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

That's right.

The Skeptics' Guide to the Universe

Yeah, otherwise you just have to like rub something against the surface back and forth a lot, and that can strengthen it as well.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

But you have to do that with jewelry.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

Same with fine silver.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

999 silver is way too soft.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

Like you can't get it hard enough.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

So only the bands, those little bezels around stones are made of fine silver because they're soft enough to like push to the stone.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

But you'd never want the shank of your ring to be fine silver.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

It would deform.

The Skeptics' Guide to the Universe
The Skeptics Guide #1084 - Apr 18 2026

Good one, man.
