A few weeks ago I put two black buffalo horn scales in a plastic bag with some hydrogen peroxide. One of the two scales is now a dark reddish amber color. The other is still nearly black, with only thin fringes of lighter coloration along the edge of the hinge-pin end.

Has anybody else tried this before? Does anybody know why one scale is having a stronger reaction to the hydrogen peroxide than the other? As progress seems to have halted on the darker scale, I am open to other methods of bleaching the scales.

Thanks.
