Effect of a Fumigant on Metal Used in Urushi Art Techniques

ȽThe Case of Mixture Fumigant of Methyl Bromide and Ethylene OxideȽ

Yoshimi KAMIYA, Hiroshi KATO and Chie SANO

The production of methyl bromide, which has been used frequently for the fumigation of cultural properties, was stopped at the end of 2004. However, it is necessary to evaluate the effect caused by its use in past fumigations of cultural properties.

In this study, the effect of fumigation was revalued by the appearance of color change on objects. Five kinds of metal samplesȝlead, tin, silver, copper, and solderȝwere processed in three ways each: simply rolled flat, processed to make a rock-like surface, and beaten with a hammer. These samples were fumigated with a mixture of methyl bromide and ethylene oxide.

The change in the surface color of these samples was examined.

The results showed that there was a possibility of color change on metal surface by exposure to fumigants.
