Charcoal Making

Here is a set of images about our charcoal making project this weekend. It is a smothered pit method, first time for myself . We did open the lower end of the pit after 5 hours and take out about 40 gallons , then we put the unburned wood back in and recovered. We will be looking at it again in about 18 hours.

This will provide us with a charcoal treatment set for our container study on charcoal as a soil additive. Surly we will not make charcoal this way again but we will have a comparison between John's pyrolyser made charcoal to our small holder method.

This charcoal as well as our other experimental ingredients will be submitted to a complete analysis routine.
