(silver like metal from the Pinto river) but was recognized as
being different from true silver because it could not be melted
(silver has a melting point of 960 deg C; platinium 1773.5 deg
C). It also caused difficulties for the Spaniards, as its
density was close to that of gold, and when gold plated it was
virtually indistinguishable from the solid metal. The
counterfieting was only brought under control by dumping all
stocks of platinium in the sea and forbidding its import into
*the six memebers of the platinium group are rhodium (Rh),
ruthenium (Ru), palladium (Pd), osmium (Os), iridium (Ir) and
