thanks for the info, but i don't need to know about evaporating metal, i
worked in metal refining for nearly 20 years as a consultant, what i do know
is that evaporative metal cannont exist on a tape, but it's resultant oxide
during its' return to liquid or solid (or pure if kept from oxygen) but
unlikely if a fine powder and thusly applied to a tape. therein, one does
not have a metal but in fact an oxide. if for example, the metal were
chromium, then the melting point and later the evaporative point would be
HIGH, which of course does not exist on a tape.
