I am working on restoring my two Clarks. One has a cracked scale and I have a piece of ivory to make a new one. The problem is the 200 year old ivory is well...ivory not pearly white like the new stuff. I read about using tea with a bit of vinegar in it to "age" new ivory. Anybody have experience with this?

The alternative would be to bleach the old stuff white but then there is the other razor. Plus, the bleaching process apparently can embrittle the ivory. That wouldn't be good. Thoughts?
