Scanning electron micrograph of traditional British lump charcoal

I have a series of scanning electron micrographs of biochar particles. This one happens to be charcoal rather than biochar. I wanted to compare commercial (traditional) lump charcoal to "proper" biochar. Structurally, they are both very similar. My view is that traditional lump charcoal produced here in Britain may be similar in chemical properties as well as physical properties as the traditional methods of productions were slow-burning, high pressure and low-oxygen.
