Here are just a few that I have done and some additional thoughts for you guys while you are attempting this:

-First I make sure that the water level is below the crown portion on the base of the horn while I am boiling, In another words I do not have any brown in the water while boiling this will require you to watch it closely and add water as it boils down to keep the level up.
-Another trick I have done that helps before I bleech is I wrap the bases of the horns with shrink wrap - I use the 2 1/2 inch stuff that comes in a roll that looks like strapping tape, This really helps keep the bleech just where you want it I go up as far as I can cause I'm allways afraid I'll spill some on the horn. I am sure you could use good ole saran wrap but it would be harder to control a big roll.


Also I use a combination of 40 volume peroxide and powderd bleech (you get this stuff at a beauty supply store- my wife is in the hair care industry.)
you mix these two ingredients into a paste texture and it is easy to control this way. Basically you paint it on where you want it to turn white and leave it on overnight and rinse it off the next day and your'e done. If it is not the desired brightness you can do it again but I have not had to all of these are only done once.

I have not messed with spraying anything on the skull after I'm done I didn't feel they needed it.


Looks like I need to dust! It will have to wait till after Thanksgiving I'm heading to Idaho in search of a big whitetail! Will post if we get something good.
