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?

    It’s a dark rock…for reasons I have lumps of coal embedded in the concrete of the basement

    I have no idea how they got there. Probably the coal used when they wete pouring the concrete left there. Again, no idea
