Dear All, I am keen to know current opinion as to what materials are considered acceptable for use in artefact storage areas. For example, is MDF considered an acceptable material to construct shelves and supports even when painted with a barrier layer of water based emulsion, and with plasterzote buffers placed between the object and MDF. Further, I would be interested to learn what people think about the use of perspex as a museum storage material, as it has an unknown life span and speed of degradation. Any information or opinion will be gratefully received. ========================================================= Important Subscriber Information: The Museum-L FAQ file is located at http://museums.state.nm.us/nmmnh/museum-l.html.
