That's the Pellet Process.... I've had many students try it, none, not
even the brightest, got it to work. In any event I advise against it,
because if you check the formula, you'll see it requires strong chemicals
(inc., as I recall k ferricyanide) for the developing solution, as apposed
to regular cyanotype which develops in water. Much better to simply
reverse your positive to negative -- With all the options of scanner,
laser printer, copy machine, press the reverse button, etc. available
today, that's MUCH easier.
