And I'm not sure how safe the leather dyes are- they are aniline or
orosol dyes, just like the stuff we use on furniture in the prop
shop,.... so, would you seal them with something???
Leather dyes are the same types of pigment used in fabric dyes, but
in an alcohol base. In truth, I've never seen a msds for the stuff,
but the denatured alcohol base is probably the most dangerous thing
in it. I'd seal them with a good wax buffing. Leather dye is
designed for items that have a lot of skin contact and handling.
Once it sets, the only thing I know of that makes these dyes crock
much is solvents.
There are a number of natural dyes that take on bone as well, but
you have to pre-treat the material with a mordant like alum, and
it's a lot more involved.
