Watch out for the dust. It's highly toxic. Wear a tight-fitting dust mask
when you work it.

I find it miserable to work, but jewelers who do a lot of it probably are
more comfortable with the stuff.

What he said, except wear a respirator- powered if possible. Lots of
shop filtration and ventilation, downdraft table with micron size
exhaust filtration is better than a plain bench. I've done a fair bit of
if for inlay and decorative pieces and will not work it without some
serious respiratory protection.

It also has a nasty burnt-hair smell when working it.
