There seems to be some confusion about the properties of metal here. Aluminium, like many other metals, only oxidises on its surface - and then the oxidation process stops. Unlike oxidised sheet steel, aluminium does not flake, and due to its light weight and durability, it is considered to be an excellent material for archival mounting purposes. Like any other metal (except gold) aluminium is relatively vulnerable to the effects of sea air, which is electrolytic - not oxidic by nature. Hope this clarifys things. best William Curwen http://www.william.ws =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
