rogerxd45 Posted December 20, 2011 Share Posted December 20, 2011 so i have a rather large chunk of chromium, well atleast thats what the seller claims it to be. i have no reason to doubt that it is chromium but i want to be positive or as positive as possible without getting it tested by expensive machines. i weighed it and it on a digital scale that is accurate to 0.1g and it weighed in at 130.8grams based on my measurements with my digital caliper it has a volume of 18.153396 and should weight 130.55291724 (and yes i know the all the extra decimal places are pointless, but im just putting down the exact numbers i got) the rectangle isnt perfect and my tools are not very expensive; so i believe that the density is consistent with the density of pure chromium. some stainless steels are about the same density and if this item isnt pure chromium i think it would be a type of stainless steel. it does not stick to a very powerful rare earth magnet, but neither do some stainless steels so that doesnt help much are there any other tests i can do to help verify the sample?

rogerxd45 Posted December 20, 2011 Author Share Posted December 20, 2011 i actually did a test with HCL with a known sample of .9995 pure Chromium and my large rectangular piece and they both reacted the same. i only let them sit in the HCL for a short period so i was able to easily remove the (for a lack of a better word) "tarnish" so now im as 99% sure its pure chromium i will try the conductivity idea though just for fun Link to comment Share on other sites More sharing options...
John Cuthber Posted December 20, 2011 Share Posted December 20, 2011 If you have an authentic sample that makes things a bit easier. Do you have a voltmeter of some sort? Link to comment Share on other sites More sharing options...
