dental scrap

[geonorts]

Hi everyone I just wanted to know what people think of this I know there is some dental scrap this colour with high Ag Pd Au and some that is just stainless steel, I want to know if you think this is just stainless or not. I can buy this but I can't test it the best I can do is I know a magnet won't stick to it

I got a bunch like that in once - they all turned out to be the cobalt nickel alloy type --- heat to red hot - when they cool if they get a rainbow color effect then that is most likely what they are - if the color does not change after cooling then they "may" be a PGM alloy but you would still want to be able to do an AR/stannous test to confirm that

Hey guys thanks, I have 44 grams now of dental scrap. I tested some, and now I have to figure out how to separate the platinum and palladium from the gold and silver. I am a newbie, and in Qatar so I have to make my little work shop. Will be giving you all progress updates. I also metal detect, scrap pcs, and do a little "dusting" of the trash piles at the gold souk were I have collect over 3 grams of broken gold jewelry in the sand.
