N2 - Samples of fresh and archeological wood were structurally characterized by XPS and NMR spectroscopy. Archaeological wood chips were recovered from excavations in the Great Temple of Mexico City. The presence of a wood consolidant (lactitol trehalose) was studied as a variable, as well as aging. Wood samples oxidized after accelerated aging, and hydrolysis was the first step that promoted oxidation. Consolidation inhibited hydrolysis and, consequently, oxidation of wood, whether contemporary or archeological.
