    Poly Vinyl acetate, works best.  There is also a product called
    Glyptal, which is used for stabilizing bone in the fossil industry. 
    the PVA is a granular product much like salt that is dissolved in
    acetone, PVA is the primary stabilizing product used in the Chinese
    turquoise industry. submerse the turquoise in the pve & use a vacuum
    setup to pull out the air & drive the pva into the chalk.  Glyptal
    also needs to be thinned as it comes in a honey like consistency.  a
    lengthy drying time is needed for both products to set up hard.
