Sources for materials

Howard Wellman asks which industries use various materials that are
also used by conservators.  The following may be helpful:

    PEG:    Various grades are used extensively in cosmetics, as a basis
            for creams etc.

    EDTA, Calgon:  Common ingredients in detergents and other
            washing products, water softeners etc.

    BTA:    Was originally used by the metal industry to inhibit
            corrosion of new copper products.  Could try metal
            foundries and suppliers.

Good luck,
