I’ve never made charcoal (but have set a bunch aside in my preps) but I do know that in colonial days where I used to live that they made beehive shaped kilns out of stones (what we have in abundance in New England), sometime big enough to walk in. After filling it with wood and starting the fire, the entrance would be sealed until the process was done.
