- Résumé
- The preservation and treatment of waterlogged archeological wood is an important topic to address because of changing climates. More and more wet archaeological materials have been exposed due to melting glaciers. For some time, waterlogged archeological wood have been most commonly treated with polyethylene glycol (PEG) or sucrose. The use of both of these compounds is known to prevent dimensional change and further degradation of wet wooden artifacts. However, each material has drawbacks. PEG has a long application process, color shifts have been observed, and more recently high relative humidity has been shown to degrade the wood compound. Sucrose has a tendency to be a pest attractant and migrates with temperature fluctuations and high relative humidity changes. Thus, due to In lieu of these preservation issues, it is pertinent to look at other materials. Recent research has been published into the application of organosilicon compounds with added active groups on waterlogged wood. Organosilicon compounds have the potential to support and stabilize dimensional change, reduce flammability, protect against decay, and reduce the impact from weathering. More recently the compounds have also been used as surface modifiers, binding agents, and adhesion builders in conjunction with nanoparticles in other conservation applications. Preliminary results showed that (3-mercaptopropyl) trimethoxysilane (MPTES) had the highest potential for the treatment of waterlogged archaeological wood, with little dimensional or color change occurring. This proposed research project further investigates the effects of MPTES on waterlogged archaeological wood after accelerated aging, by exposing prepared wood samples to high relative humidity, at 100% RH for four days. The longterm preservation capabilities of the MPTES were analyzed by examining weight gain, color change, dimensional changes, and biodeterioration of the wood samples. These changes were examined with various techniques including Fourier transform infrared spectroscopy, Hirox microscopy, light microscopy, scanning electron microscopy, color photometry, and a digital scale. Results indicate there was a significant decrease between initial weight and after airdrying for MPTES/ethanol treated samples, however the difference is not as drastic as untreated samples. Color difference is minimal in both the treated and untreated samples. Initial visual observations indicate minimal dimensional changes to the treated wood, however drastic detrimental changes to the untreated samples.
