Hi there,
I found a documentary about the char-coaling process, so I guess this is the right thread for it. It shows a factory (already 82 years old) with retorts and the old charcoal pile-style in a living history museum. Both are located in Germany and the language is German, so maybe this is of medium interest due to the language barrier for most of you. However, there are some nice pictures in this video.
Kind reagrds,
