Richard,

Thanks for reminder about film sticking to the inside of the tube... I
should have recalled that note because I've sold over 450 copies of Gordon's
Pyro book to C&D readers in the past few years.

The question of "stain" is becoming debatable with some people... I know of
two platinum workers who no longer reuse the used pyro after the fixing
bath... doing so simply produces TOO MUCH stain for their liking and needs.
