I have a correspondent who tells me that in about 1990 there was a trial in
which some elderly African "steelmakers" used a 19th century furnace to
produce some "steel" and that this was filmed (perhaps for TV).
Does anyone know anything about this trial? I would have thought it was more
likely to produce iron but I am not familiar with African processes.
I do know that steel can be made in a primitive furnace.
