6I have discovered a growing interest in bone cleaning, de-greasing and preservation by artisans, jewelry makers and collectors who use bone and skulls as a media for their crafts. Many of these people are new comers to bone work and lack the basic knowledge to produce grease free, sanitary products. In some cases, this can leave an artist creating a piece of art that in time can develop odors like rancid fat, turn dirty yellow and it may actually grow mold. I wrote this manual to provide easy to understand information geared to beginners as well as others who are looking for a better or new way to preserve skulls and bones with as little damage as possible. This book gives you the basics and more.
