[QUOTE="AngerManagement, post: 462312, member: 3760"] This is a reasonable reference... [url]http://www.ambrsoft.com/CalcPhysics/Density/Table_2.htm[/url] But again there are variables... Quality of water and most importantly the quality of the scales- should have 2 dec places at least and 3 is great if you can afford it. Due to other impurities and your method and accuracy, you may not get an exact mach but if your close to the numbers. Then you are 99% there. As you will see Tungsten is close and hence why many fake gold bars have a core of Tungsten and without a good meteorological ultrasonic tester... A simple scratch test or weight or density test will not always pick up the fact that your Perth Mint bar that you got from scambay is 100% or NOT. [/QUOTE]
