The best way to make charcoal-super easy

Opis:
The easiest way ever to make charcoal that is clean and ready to use for whatever you want. Just buy a cast iron dutch oven and load it with the clean dry wood. Stick it on a fire and build it up around it.The heavy lid will let the volatiles boil off and seep out but wont let the air inside to make the wood catch on fire. So the wood continues to have the gases cook out until its almost all carbon. You can use any steel container of any size and stab a hole in it. It will quickly heat up in a fire and start off gassing and not let any air in even though there is a big hole. just plug it with a wet paper towel after you take it off to cool
