I also found B-72 rather too sticky for porous and friable bone and
prefer HMG as adhesive. Our museum conservator suggested using a
consolidant (Paraloid B-72 diluted with acetone) in several coats
prior to gluing, with the first coat very dilute. Worked well and is
reversible, but of course the treated bone cannot then be used for
carbon dating or other isotope studies.
