I can confirm what JonE said, it's actually quite hard to get the ceramic out of a modern plug. I did it recently to make lifting eyes to lift the engine in and out and it took some time to actually remove it. If you're chipping away at it it is definitely one of those times where eye protection is required!
Another method I have heard of but never tried or seen is attaching some kind of air hose fitting to an old spark plug then using an air line from a compressor to pop it off. As when using the engine compression to do it you loosen the head stud nuts but leave them on so the head doesn't go flying.
