I'm an art student who recently came into possession of an entire head (almost life sized) sculpted out of beeswax. It was given to me to re-use the beeswax in a project, but when I started to peel it down and melt the wax in a crockpot, I received a nasty surprise. There was a large part on the inside of the wax head that smelled just terrible (think fermented smell) and a few tablespoons of liquid seeped out. Also part of the wax is black and very hard. I really want to use the wax, is there any way to salvage it? Seriously guys the smell is headache inducing.
