Heat usually distorts the cartridge, or in some cases completely melts it. What I would do, if I were you, would be to get a bunch of empty cartridges or sacrificial tapes and remove the magnetic tape spools, replacing them with the ones you want to keep. It is easiest if the cartridges are assembled wih screws, because then the two halves can be easily separated and reassembled. But I find even those that are glued together can be split pretty easily with a razor blade, and then reassembled with glue. Just be careful.
