This is a time-lapse video of Niall Kenny and Eoin Donnelly's experimental charcoal production pit at Smelt 2010 being opened and emptied. The charcoal burn went well and a substantial amount of charcoal was made. The charcoal burn was featured in the Naked Archaeology Podcast which can be downloaded here or listened to online here.
More updates on the charcoal experiments will be put up asap and you can have a look at some video from the smelt here.
