That doesnt turn liquid though
Nah, it just bubbled up into a sphere like that while in solid rock form, obviously.
It made glass.... not melted rock that reformed into rock.
Given that it is composed of multiple substances, as you referenced in another reply, and these substances were separated by heating, it would not just reform back into it's whole form. It fucking melted.
If your argument is that some substances melt, and others do not, just say so. Saying rocks don't melt though is disingenuous.
