| Abstract: | This study looks at the residues of heated organic remains, usually called carbonized or charred remains, and focuses on the physical and chemical alterations, both as a function of temperature and time, that occur when the transformation of a polysaccharide-rich biomass is simulated in the laboratory. Peas (Pisum sativum) were heated at temperatures ranging from 130--700 °C under anoxic conditions and atmospheric pressure, during a maximum of 2 h. Changes in weight and the relative percentages of C, N, H and O were noted alongside modifications of the internal and external morphology. Vitrinite reflectance provided a tool to determine the heating temperature of the residues. The kinetics that determine the changes and modifications are discussed. The resulting solid products of the heating process can be conveniently considered in five phases, which fit the physical and chemical properties. The simulation provides a basis for the study of the formation processes, as applied in archaeology, after the so-called "carbonization" process. | ||||
