In museums the installation of wooden display cabinets is prohibited due to the VOC’s and their corrosive effects on metals -especially lead. Regularly all materials have to pass the obligatory standard Oddy test which guaranties the material suitability, considering the sensitivity of museum area. Therefore, emission of VOCs of wooden display cabinets in museums need to be reduced and prevented.
In a previous study wood-specimens were sawn, impregnated with alkaline buffer and dried in either vacuum drying or conventional drying processes. The results of the Oddy-test showed variable corrosive decomposition of the lead-coupon which were part of the Oddy-test set up. In the present test series natural and kiln dried wood-specimens were impregnated with neutral buffers and dried after impregnation at indoor climate. Regarding the different drying- conditions of the raw materials, the aim was to determine adapted buffer capacities.
