Bone material is usually allowed to remain untouched by attempts to make it whole due to the ethical concerns. This is felt in many circles, especially regarding human remains, since infills will hide some of the history of the object. The infilling proposed in my research was for faunal collections that would be displayed in natural history museums. They would not be used for study, and would be more aesthetically pleasing to the eye if they were whole.
The materials tested were: Flugger, dental plaster, and B-72 mixed with microballoons.
