Don't use Biz. See Shelton and Buckley, Collection Forum, Society for the Prservation of Natural History Collections for a paper on the awful effects it had on what was supposed to be a collection of rare fish bones but was instead rare fish bone powder. There is also work at the Conservation Analytical Laboratory in press that backs many of our conclusions. It is a proprietary product, which means that you don't know and often can't find out whjat's in it; it is not made for the purpose of osteo prep; it caused intractable blue-green staining in everything from camel to bat bones at a variety of sites; and it needs to be denatured and hardly ever is. Please avoid this preparation. It is based on an outdated and poorly tested paper.
