Lead in water makes the water taste sweet. My guess is that they charred lead dust to make it look grey/black and then used it as artificial sweetener.
The carbon comes from another source and sticks to the metal, you’ve probably already seen examples irl. If you burn something in a steel pan on the stove, then there will be black residue (char) left sticking on the pan. A burnt electrical outlet is another case, there the carbon comes from the plastic.

Thanks. I wonder how it’s even possible to char a metal.

Thanks for the cast iron pan comparison, I think I get it now.
