Progress Research on Bio-deterioration of Historic Architectural Glasses

Song Gang, Yang Changming and Zhang Aili

This study attempts to guide and promote the future research on bio-corrosion prevention and cleaning techniques of historic architectural glasses, while there are no domestic relative researches reported now. Firstly, the author demonstrates that the bio-deterioration of glasses does exist according to references and its degradation consequences can not be ignored. It systematically analyzes the recent abroad relative researches and gets the conclusions that there are three main bio-deterioration impacts on historic architectural glasses, i.e., the decreasing in the transparency and thickness of the glasses and changing of the tinct. Then we get the main bio-deterioration forms, the bio-films covering, incrustation mineralization of microbial metabolites and mechanical disruption caused by microbial growth in the micro-fractures on glasses surfaces. Furthermore, the bio-deterioration mechanism of glasses with a visualized figure is given out. We also introduce the latest applications of molecular biology experimental technique in this research field and points out the newly developed glass cleaning techniques, including laser cleaning and the disadvantages both in expensive costs and operations. Based on the above analysis, it also prospects the bio-deterioration research of historic architectural glasses and research of specific domestic regions, researches on reservation cleaning technologies and accelerated laboratory test of bio-deterioration.
