Yesterday, I tried my darnedest to get it cleaned up and ready to whiten, but I still have some gunk stunk in the brain cavity and up the nostrils. The problem I think was my pot was too deep and I couldn't have the whole skull in the water long enough. Seems to be the best method is probably to use the beetles, which I don't have. I'm going to give this another shot tomorrow and hopefully be able to whiten it as well. A member of our church owns a sawmill that specializes in cedar, so I am hoping to get a piece of wood from him and make my own plaque.
It looks like I'm done but actually there's too much in the skull to whiten yet.
