I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for charcoal that I've seen before include "Black residue of burnt wood" , "Artist's black material" , "It's made by burners for use in burners" , "It's used in drawing and barbecues" , "Kind of fuel made by burning wood" .)
