A top-of-the-line fake gold bar should match the color, surface hardness, density, chemical, and nuclear properties of gold perfectly. To do this, you could could start with a tungsten slug about 1/8-inch smaller in each dimension than the gold bar you want, then cast a 1/16-inch layer of real pure gold all around it. This bar would feel right in the hand, it would have a dead ring when knocked as gold should, it would test right chemically, it would weigh *exactly* the right amount, and though I don’t know this for sure, I think it would also pass an x-ray fluorescence scan, the 1/16” layer of pure gold being enough to stop the x-rays from reaching any tungsten. You’d pretty much have to drill it to find out it’s fake. Source.
Your revolution is over, Mr. Stark. Condolences. The bums lost. My advice is to do what your parents did; get a job, sir. The bums will always lose. Do you hear me, Stark?
