Dont boil or bury. look here
http://www.taxidermy.net/forum/index...c,48226.0.html . These are people who do skulls daily. Nearly everyone will tell you the best way to get good results with european mounts is to use beetles or a process of maceration. Don't boil because it severely softens the bone to where it may break if you don't know what your doing (also kinda risky to do on younger deer due to there thinner skulls and bones). Burying may produce an ok result but alot of the time you have leathering and certain areas that don't decay all the way. Maceration (breeding bacteria in water), may be the simplest do-it-yourself method. just put your skull in water with a heater and change 1/3-1/4 of the water every week. A little stinky but produces a fantastic result. Check out the Skulls and bones section of taxidermy.net/forum
