Hi all,
This is my first post for several years, it's nice to be back.
There is a building site in a French forest where a 12th century castle is bering built from scratch using techniques, methods and tools of the era. Most materials are processed and made from what is available locally.
There are several episodes on the extraction of iron using a primitive blast furnace which may be of interest. They are from the first series, episodes 6,7,and 8. The program is in French but with English subtitles. You may find it of interest.
I hope that you enjoy them – keep safe,
TerryD
