I cleaned my skull sometime ago in preparation for a Euro Mount. It came out really good and is nice and clean and nearly white. It sit around now for nearly two years and before I got it bleached I accidently knocked it off of a chair and it landed directly on the nose smashing off the orbital bones. I have most of the pieces and they fit back together like a jigsaw puzzle. What is the best glue to glue them back in place bearing in mind they are small with not a lot of surface area for glue. Also, what is the best filler to use to fill in where small chips may be missing. I thought of Sheetrock 90 but I doubt it would work.
