(Author’s own data)

Plots of mass loss against temperature for modern (left) and degraded archaeological wood from Glastonbury Lake Village (centre) and Flag Fen (right), obtained by TG analysis. The slope indicated by ‘A’ indicates loss of water, and the slope at ‘B’ relates to cellulose loss. The slow mass loss after 400 °C is caused by lignin loss, and any remaining mass is inorganic, or ‘ash’ components.
