Hi all. I often see things like fish skulls and snake skeletons being dried before being beetle cleaned so that the skeleton remains in position. My question is, does anyone know how to whiten a skeleton like this while keeping it in this position? I get skeletons out of the beetles looking great, and they stay together when I degrease them in acetone, but I can’t figure out how to whiten them without the cartilage softening. Every time I put them in peroxide they come out limp and falling apart and have to be re positioned. Hope this makes sense, thanks for any help.
