I think I know the answer to the question, but I will toss it out there anyway.
Can you use coal in the BGE?
A friend of mine is getting rid of a giant pile of coal that has lived in her basement for a long time-since the days when coal was the go to choice for heating.
Could you mix it with lump to get a higher temp with less lump?
I am guessing it is safe to cook with for my grandads stove/oven was a coal burner. And what about coal fired pizza ovens?
If not safe for the BGE what about tossing a couple in a camp fire?
