Hello /sci/ Do we have any geologists in the house?? Anyone know what this is? I know its volcanic and most likely from japan.
It's a rock

I can confirm that while it is a rock, it is not meth. So we can rule that out.
Im pretty sure at least
Could be some sort of slag from smelting. Different colors are different temperatures at which it cooled?
Slag glass

I'm thinking slag glass is likely, but I could see it maybe being some form of agate?
