I'm doing a horn for a friend..plug in, scrimshaw done, decided horn was just too white. Had a solution of "Old Bones" on hand, put horn in. After 3-4 hours,barely any color. Dumped the rest of the Old Bones bottle into the solution, put horn in, and forgot it for about 5 hours..horn came out so dark brown it looked like mahogany. Scrimshaw can't be seen. Made a strong solution of Chlorox and put horn in. 4 hours has brought it to the light tan look I wanted. Should anyone else suffer from senior ADD and so screw up, I pass on this solution. Hank
