English: Charcoal burning platform Small flat platforms in hillsides are a common feature of forests in Britain and France. They are where charcoal was made. This is a demonstration of a charcoal oven in Glen Nant, the wood being heated in a near absence of oxygen to produce charcoal, almost pure carbon. The charcoal was used for iron smelting.
Areas with ironworks have often retained native woodlands. The burners knew better than to destroy their source of income.
The timber was produced by coppicing on a 20 year cycle. According to the board at this site, 30ha of forest was coppiced in a year. 1 ha producing 27 tonnes of timber which then made 4 tonnes of charcoal.
