I use a dremel and cut right through the flesh on top of the chalice. I add a bit of water while I am doing this to keep the heat down on the fleshy part of the chalice. I cut down as far as I can into the skeleton. I then take a small chisle and place it in the cut, one easy hit with a hammer and the piece pops off totally clean and good to go. I usually use a soft toothbrush to clean up both the pieces at the wound site, getting all the dust and bits of rock/skeleton off. I then put them both in a TMPCC dip for ten minutes and back into the tank. This method works like a charm for all of my chalices and encrusting montis.
