I have seen many posts on here about hogs and skull mounting. I use a good old crawfish boiling pot and boil the head for about 3 hours, gets all the skin and meet right off. After it dries out, soak in in clorox.
Not trying to be a "know it all" guys but it will look GREAT at first but will begin to turn yellow in just a few weeks or months. You have to degrease! Hogs and Bears are the worst when it comes to grease.
Clorox will also "yellow" the bone and make it brittle. Use Peroxide and Basic White.
Listen to the taxidermist, your stuff has grease from the bone marrow in the jaw and other grease in the snout. Cooking doesn't get rid of it. Clorox immediately begins to degrade the bone and attachments such as seams ("sutures") of the skull parts. Spraying laquer or varathane or other sealer does arrest the decay from clorox, but since you did not neutralize theclorox first, you locked in the decay. I had a cooked and cloroxed boar skull with 4" unpulled tusks that looked great for 3 years under several coats of plasticote clear spray, then in the jaw started yellowing and a couple years later it fell apart and grease came to the bone surface in several places. The clorox also makes the tusks break into 3 parts.
I just bury mine for three months in a active worm area, plus ants. Let them do the dirty work. Then dig it up carefully, hose it off and clean it up, then let it dry. I then use the peroxide that hair dressers use and saturate it in that stuff, let it dry and hang them up outside on my decks and trees. Other than the nose bones falling off I have had ok luck with them, some are going on like 3-4 years now.
its amazing how many skull mounts i get in my shop to finish cause of all these home remedies that float around. The only right way to do a skull is to use the right chemicals. The more you cook it the more you destroy the connective tissue that holds the bones together. And makes the bones very brittle.
not trying to be an ass but i don't see the connection between proper skull cleaning techniques and introducing youth to hunting. like xtremewhitetails said you have to use proper chemicals to ensure a long lasting mount. sure there are different methods. i personally macerate all of my european mounts, but they still need to be degreased and whitened properly.
Plaisance, I learned two years ago that maceration was the way to go. A lot nastier but less destructive to the bone and a lot less time consuming. I have up to 20 skulls macerating at one time and can do something else (regular job) while the bacteria do the work for me.
I have actually had to re-do some of my own work. Just when you think you have all the grease out then a couple of months down the road here comes a couple of nasty spots!
I have macerated skulls in a 5-gallon bucket of water put on a roof top where the animals could not get to it and the smell would not bother others. However, I knew a guy that put them in a compost pile that was mostly used pine shavings from horse stalls. His came out better, except he had to search around for the small teeth that fell out. He had a situation where dogs and other animals could not get to his compost pile to dig the stuff up.
