Default lost wax process

i have a couple of 'cap packages' that are stuffed w/wax -- or
whatever the brown goo is-- like the kind used to seal slugs in tuned
coils.

one is a bakelite case, the other a metal box, both w/the caps and
leads buried in the goo, which seals the bottom of each case. the
metal box one is a cornell-dubilier.

is there an easy to remove the goo -- maybe by melting it out? want
to see the innards clearly before pulling the caps so i can rebuild
correctly. cap values are known -- mostly a matter of seeing how the
leads connect and how insulated from the case for the metal one.

I use a heat gun and patience, but others who restore vintage
radios set the case or box suspended above a pan in the oven at
about 200 or so degrees F, and wait an hour or two. If Mrs. is out
of town when you do it, that's a good thing ;)
