I m not really in the know on this subject but would like to try some things with some bone that I purchased. I bought it to carve, but it has been bleached and whatever process they used to bleach the bone left it very dry and brittle. It is not nice to work with at all. I soaked a couple of pieces in some light mineral oil and on the surface they are much nicer they need better penetration. I don't want to sink a ton into the project, and I have a vacuum pump. As long as I am not dealing with any glass part it should be simple enough to rig up an airtight container to do my trials in. So here is my silly question, is there anyone with experience following this or perhaps B52 may have had some early experiments along these lines that I could gleam a little info from.
