Subject: Sealing cement
I think one of the articles to which Ellen McCrady referred (in response to Michael McColgin's query) that offers research done in Japan into atmospheric contaminants from freshly poured cement is: Toshiko Kenjo, "Certain Deterioration Factors for Works of Art and Simple Devices to Monitor Them," The International Journal of Museum Management and Curatorship (1986), vol. 5, pp. 295-300. His study found that linseed oil impregnated paper darkened significantly (denatured and saponified) when exposed for year and a half to the atmosphere in a newly poured, unsealed concrete building. Not until the building had stood for more that eighteen months did the atmosphere regain acceptable museum conditions. Silk and certain pigments deteriorated as well. The article does not mention photographic materials. The offgassing effects of freshly cut wood are also discussed. Hope this is a help. Nancy Turner, Manuscripts Dept. J.
