I took a look at the coal I made and the epilogue is.
The cans on the sides don’t get enough heating (one can hard almost no carbonization)
Big logs is much harder to turn into coal then “sticks”.
Paper in the can seems to isolate and prevent the wood to reach the right temperature.
Dust mask and gloves would not be to bad.
Retorting and insulation and some way to use the excessive heat would make charcoal making a bit more useful.
