Soft Metals Hardness

[kitcik]

The way glass was made in the middle ages, it would shatter and you would have glass shards in your hands (or mouth, if you somehow sucking the air out).

Also, if you drained the bottom half of air, it'd still be full, because the bottom half has water, not air. Unless you turned it upside down, in which case, you'd have a lot of draining to do.

I'd fill the top half with water of course.

Or what if I sealed it on the top and then drained all the air so the glass would be filled with half-density water .

Aren't we supposed to talk about metal though?

Core rulebooks have Bronze, Iron/Steel, Mithral and Adamantine, rest is probably guesswork. Probably only cause those metals are made for armor and weapons.
