Thank-you for your responses, here's the information I received:
1. Charcoal itself does not contain gluten. Charcoal briquettes are
usually made with wheat flour as a binder. Try using fireplace wood, it
makes the food taste better than charcal.
2. Get solid charcoal, not the briquettes. You can buy at a hardware store
it may be expensive.
3. Get hardwood charcoal at the grocery store, sometimes Wal-Mart has it.
4. When the charcoal burns the original substance is chemically destroyed.
5. Cooking with charcoal isn't safe regardless if it has wheat in it or
not.
I am going to go ahead and use my Kingsford. I don't think the wheat that
it is bound with will get on my food via the smoke. If I get sick I will
use pure charcoal as suggested or get a gas grill. Thanks Janet
