Hello all... I'm still working on the collection of wax cylinders which I've asked about on this list before. I have a (hopefully) specific question: What precisely are the cylinders made of? I seem to recall reading that they were made of different things over the years, from the earliest ones that were truly wax to the later ones which were, well, that's my question I guess. Most of the ones I'm working with are of the kind pictured on this page in the upper right corner: http://www.tinfoil.com/gallery.htm#top I'm asking because the conservator I'm working with wants to try a chemical treatment on them, but she wants to know exactly what kind of material we're dealing with, and more importantly if it may be harmed by ethylene oxide (either short term or long term). If there is too great a risk, we'll skip that idea, but I thought I'd throw it out to the list and see what people have to say. Thanks. ------------- Trey Bunn Folklife Resource Center McKissick Museum University of South Carolina __________________________________ Yahoo!
