Sandy and Joe,
Small amounts of oxalic acid and EDTA (I use .5 gram each when making
50ml of ferric oxalate) are helpful and actually beneficial to the
solution when printing in Pt/Pd. It seems best to help the stuff get
into solution with a shake, wait, shake approach, even leaving it
overnight. If that doesn't work, gentle heating on a small hotplate or
by giving just a few seconds in a microwave, followed by shaking, will
get the job done. Different batches of powder from different sources
will vary greatly in ease of dissolving.---Carl
