I would LOVE to have some of this LUMP...wonder what shipping from that part of the world would cost? Ouch. http://www.graigfarm.co.uk/
Produced close to Graig Farm on the English/Welsh border, their charcoal is produced by an independent producer, Woz Young, who works alone to produce high quality, sustainable hardwood charcoal.
It is produced with materials sourced from sustainably managed woodlands. These hard woods are produced by the practice of coppicing (cutting stems on a 10-15 year cycle), thinnings (removal of poor quality stems in a stand), and 'Lop and Top' (waste material from mature felled timber).
Small diameter materials are preferred. These are then slow cooked in situ in large steel bins for 24-36 hours, removing all moisture and volatile gasses from the wood, leaving its basic carbon structure - charcoal.
The charcoal relights and burns well at far greater temperatures than the original wood and without the smoke. It also weighs 1/6th of the weight of the wood.
Charcoal can be used for a variety of purposes, including drawing, dying, smelting metals and water purification and improving the quality of our local native woodlands.
