Any of you briar alchemists out there interested in trying to track down critical data about potential hazards of working with ivory? Aside from the fact that it is particularly noxious, I am interested in whether or not the dust is hazardous. Any takers?

Calcium and protein, a few minerals, hmmm. Why do you suspect that it may be hazardous? Are you experiencing a reaction? As one who experiences some allergic problems, I can offer a couple of general comments. An individual may experience an adverse reaction to any particulate matter that is inhaled. Some substances trigger receptors that release a histamine response. Mold spores, wood dust, dust mite feces, pollen, etc. Others trigger a vascular/motor response (runny nose, cough) that is often mistaken for an allergy -- many people who say they are "allergic" to smoke actually are experiencing this sort of irritation. Other substances, like sandblasting media, may be chemically inert, but quite damaging to lung tissue. Still others actively damage cells. Plutonium dust would be an extreme example, but organic compounds like toluene are pretty bad, too.
I would eliminate this last problem when considering ivory's potential hazards. Also, I would doubt that it is likely to cause lung damage like silicosis. It is durable, but biodegradable. The other potential problems depend to a great extent, I would expect, on the individual.
FWIW, I wear a respirator whenever I'm generating fine dust that can't be collected effectively. In working with ivory, I try to use sharp tools as much as possible and minimize sanding, so that I'm dealing with shavings more than dust. It should be clear by now that I'm not going to actually do any research, here : ) . However, if I *had* to research this, I'd search whatever journals and archives are maintained for/by dentists. Certainly ivory has been worked for hundreds of years, but most of the work has been carving, which doesn't raise much dust. However, dentists are grinding teeth all day.
