(commonly about 23%MC) so there is no water in the cell lumens, nor are the cell walls fully saturated, which is why there is low risk of harm from a freezing `mechanism' (commonly imagined as the 10% ice formation expansion) to your material. Sincerely, Tom Strang Canadian Conservation Institute

was carried out. Quite a different scenario to the dry and nominally intact samples used by Tanimura and Yamaguchi. Currently in Japan, urushi objects are likely to be treated by CAF (controlled atmosphere fumigation) methods, either low oxygen or CO2. Sincerely, Tom Strang Canadian Conservation
