I work with jewelry fabrication...What's this about platinum being dangerously flammable? Pure platinum is not suitable for jewelry, too soft, so we alloy in 10% iridium to strengthen it. To do this, we smelt the iridium and platinum in a crucible with a blazing hot flame put directly onto the metal... we're talking very high heat of 3,215°F/1,768°CI've never had my pure 99.995% platinum ignite or explode while alloying it to .900 plat.Sooo... what do you mean "don't use platinum around flammable materials"? I put an oxygen accelerated torch directly on the platinum without it going kaboom.
