Use surface decalcification:
Surface the block, then remove from the microtome. Do not use the
microtome for another block, so as to avoid adjusting the position of
the block face to the knife.
Place the block face down in 4% nitric acid for 2 hours or longer.
Rinse the block and cool down.
Place back into the microtome. Use a fresh blade to ensure sharpness.
You should be able to get 3 or 4 sections at 5 microns before hitting
the calcium again.

Does anyone know if there is a method to decalcify bone once it is FFPE?
