“…Nonetheless, it is well known that thermal decomposition of wood is accompanied by major chemical changes in hygroscopicity, viscosity, cell wall structure, color, density, and loss of mass and strength [4][5][6][7][8]. Moreover, it is also documented that these alterations depend on variables related not only on the wood, such as density, moisture content, permeability, species, size, grain direction, and surface protection [7,9], but also on the heating scenario, which incorporates the heat flux (temperature and duration) and the environment surrounding the wood like the oxygen concentration [7,[9][10][11][12][13]. All these factors which influence pyrolysis, combustion, and the charring rate of wood justify the coexistence of charred, semi-charred, and uncharred wood in the shipwreck.…”
