I just realised that I have never seen or used it, neither crude oil of course, but there are more variants of it than this natural mineral that powers a lot of the world.
What led to you seeing or touching coal?

Closest I’ve ever seen outside of pictures of coal or digital representations of it would be charcoal, for grilling. Otherwise, I’ve never seen it, unless I saw it once in a geology class I did in the fall and don’t remember it.
