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?

    I looked up “coal garden” and it unlocked a memory from my childhood. I think my older sister had a science experiment type of toy that grew crystals like that.

      They’re not uncommon among the other “Crystal/Mineral Aquarium” experiments! They can grow some stunning structures over time, but moving them without damaging the growth can be a bit of an issue.
