Charcoal
was the world’s first industrial fuel (for metal working). It
has been produced and used in the UK over much of the last five thousand
years. During this time there has been increasing pressure on
timber supplies and use of land for agriculture, both of which have
made necessary the effective management of woodlands through coppicing.
Coppice material was of regular size, was easy to handle and required
minimal recutting. Collection and preparation of the right timber was
important to ensure consistent high quality. Denser broadleaved hardwoods
were preferred since they produced a high quality charcoal which would
burn hotter for longer.
Woodcolliers
mostly operated and lived in the woodlands stacking the coppiced wood
to create a pile or “clamp” over six feet tall and twenty
feet across which was covered in turf and earth to control the burn.
Great skill and experience was required
to carefully tend the burn both day and night for up to a week to create
pure charcoal rather than a pile of ash. A sudden change in wind could
result in a flare-up and the destruction of a week’s patient work
so they often worked in pairs, one keeping watch whilst the other slept
nearby.
Experimentation
in the conversion of coal resulted in 1735 in the creation of coke.
This new fuel quickly became preferred and contributed to the decline
in use of charcoal. Within a century most of the furnaces had converted
and over four thousand years of charcoal use as an industrial fuel came
gradually to a close. Sadly, this combined with a decline in demand
for woodland coppice produce left most ancient woodlands, especially
in southern England, abandoned coppice with declining wildlife.
A.A.Milne,
famous for his stories about Winnie-the-Pooh, immortalised this rural
craft with his poem “The Charcoal-Burner” published in 1927.
It is believed the poem was based on a woodcollier who lived and worked
near Ashdown Forest in Sussex, but already he was part of a dying breed.
In the year 1282, there were nine hundred charcoal
burners in the Forest of Dean alone; in 2002 there were less than three
hundred in the whole of the UK.

Thankfully,
a recognition of the benefits of coppiced woodland and ecological
impacts associated with imported charcoal is helping to support
these woodcolliers, maintaining local jobs and craft skills. Small
and mobile metal kilns, introduced after the First World War to
reduce the burn time to less than 24 hours, increase yields and
improve safety, are now most often used instead of the traditional
clamp, yet all the skills and experience are still needed to control
the burn and the resulting quality of the charcoal. Many
people believe that retaining our countryside heritage with locally
based industries promotes a greater sense of wellbeing amongst
the community, forging links between our pasts and our futures.
Over the last few decades the ancient woodland industry of charcoal
burning has been relegated to museums, while we continue to import
charcoal from tropical rainforest swamps.
Think this is crazy? Then think local for charcoal. |
