1) I have been told that carbon microphones can be revitalized by leaving them
in an oven for an hour or so at a temperature of about 180 F. Did anyone try to
do that? It would be easier to put the entire microphone in the oven rather than
just the capsule, but I am not sure on whether this could cause damages to the
non-metallic parts

I've never heard that, but back when telepehones uses carbon mikes, it was
popular to fix them by removing the cartridge inside, and banging the
cartridge on a table top.
