Has anyone had any experience with Le Creuset/charcoal grills? Want to put the Le Creuset Signature (black) on a charcoal grill on the top grate with more than 6 cm distance to the charcoal (no fire), e.g. to cook pasta. The grill is the Petromax Atago. There is already a question in this direction, but the answers are contradictory. I understand that the pot won't win any beauty prizes afterwards, I'm more concerned with whether the material is damaged or not. :-) Merci!
