An Odd Question - Re: processors

Hello all. If there is a better group to post this to, please let me know.
Whilst dump picking at my local transfer station I have developed a nice
little collection of processors. I like to "pop the top" of the processor to
expose the microchip for viewing. Now the 386, 486, Intel & AMD processors
have a copper shield over the chip that flicks right off with a sharp chisel
and a tap hammer, nice and clean. But I recently pulled a Pentium out of the
pile and this sucker has a ceramic shield that seems to be welded on the
thing. I finally got it off but not before cracking the entire chip. Does
anyone know of a way to remove the shield on these (and I am assuming
higher) chips? Some kind of solvent perhaps?
TIA.

don't know of any solvent that will dissolve ceramic...

maybe you can grind the top off until the chip inside is exposed

of course the warranty will be voided :)

I just checked. The warranty doesn't say a thing about going at the
processor with a hammer and chisel. I'm covered. ;-P
