I only said "copper vapor" in lieu of my little "variac" story above, to fit in with
twobob's off-topic topic concatenation.
I have a bunch of old coax with silver core and silver braid. But it is obsolete. I use LMR-400 these days. Very limited waveguide collection at this time...
And besides, a glass waveguide would look prettier with gold than with copper.
