Wood retains most of its qualitative features when charred, but the dimensions and appearance of the cells change in various ways. Wood density, anatomical structure, moisture content, duration and temperature all influence wood behaviour when charred. This paper explores the qualitative changes that take place in the wood of Mimosa ophthalmocentra and M. tenuiflora when charred artificially at temperatures of 400, 600 and 800 °C and compares them with charcoal produced in a traditional temporary kiln in northeast Brazil. Our findings can be applied to interpreting the conditions in which charcoal has been produced, and document what happens qualitatively to the vessels, fibres, axial parenchyma and rays in very dense Mimosa wood (>1.00). The observations are specific to these two species.
