Each year wood from oak is burned in a controlled manner to produce charcoal for barbecuing in Turkey's northwestern province of Edirne.
The wood is sorted by size and then stacked in a cone-like shape.
The hill of wood is then sealed off with soil and hay, leaving only a small hole up on top...
...where they throw in some embers to burn the wood in a controlled manner.
This burning is a very slow process, taking 10 to 13 days.
The workers work in shifts to make sure that there is no leaking of smoke during that burning period.
Workers watch over the hill of wood 24 hours, 7 days a week.
When a leak is found they fill the hole with some earth, stomping it shut with their feet.
The better the wood is sealed off in this process the better the quality of the charcoal will be.
Once the burning has finished the workers start packing the charcoal into sacks.
One sack costs about TL 150 ($11.93).
From one such wooden hill, about 22 tons of charcoal can be produced.
Workers shovel the finished charcoal.
A worker closes off the filled sacks of charcoal.
