Hi Peggy
1. I have found that to cut  bone the block has to be REALLY cold. Face
block with increased knife angle as suggested by Rene, and then place in
freezer overnight - then try sectioning
2. Try surface decalcification of your block overnight in whichever soln.
you normally use.
3. Section at 4-6 microns
4. You do not say, but high profile disposables work better with bone than
low profile
5, failing this, you could try dewaxing and re decalcifying for a few more

good luck
