websites ect for buying bone?

The problem is the cleaning of the bone it isnt pure white, if you have a bone with meat on and even if you boil it ,but Iam working on that one :? hmm. Horn and antler is no problem to obtain here.Also the bone is not the same as in Ancient times it is less dense, so some items deep carved you need to be lucky to find a good piece to work with.

If you add some caustic soda granules (sodium hydroxide- should be able to get these from a chemists/ some hardware stores) to the water before boiling the bones it will strip the bones and leave them really clean, it is a very good degreasing agent. It shouldn't weaken the bones either. I'm not sure how much you add, try different concentrations.
Just be careful it doesn't splash in your eyes or skin.
