Conservation of wooden artifacts: evaluation of modern and classical materials

Conservation of wooden artifacts represents a common goal for researchers involved in cultural heritage studies all over the world. Unlike some other types of artifacts, such as natural or man-made stone, the wooden ones are much more exposed to degradation. The present work establishes the potential application for the treatment of wooden artifacts of some commercially consolidants, as well as of a traditional method. By evaluating the effects of the treatment on wooden artifacts models (using optical microscopy, Fourier transform infrared spectroscopy, thermal analyses and dynamic mechanical analysis) as well as their resistance towards staining materials and the overall aesthetic alteration, the best method can be proposed for the treatment of historical wood. The wooden models used for the experiments consisted of wood spatulas with standard dimensions (150x18x1.6 mm), on which six potential treatments were applied by immersion. By corroborating the results obtained and the evaluation of the recorded aesthetic changes, a proper treatment can be proposed.
