Imagine if you could? Everyone would do it. When you take your gold to the gold buyer how does he know you haven't painted something gold? He has a little scanning thing he can differ between different qualities and % of gold. |

X-rays don't really exist, it's all just satan's work. |

Anonymous Coward User ID: 820045 Germany 11/16/2009 02:58 PM Report Abusive Post Report Copyright Violation | [link to www.popsci.com] 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. (Unless, of course, central bank gold inspectors are wise to this trick and have developed a test for it: Something involving speed of sound say, or more powerful x-rays, or perhaps neutron activation analysis. If bars like this are actually a common problem, you certainly could devise a quick, non-destructive test for them, and for all I know, they have. Except, apparently, in Ethiopia.) Such a top-quality fake London good delivery bar would cost about $50,000 to produce because it's got a lot of real gold in it, but you'd still make a nice profit considering that a real one is worth closer to $400,000. A lower budget version could be made by using the same under-sized tungsten slug but casting lead-antimony alloy around it (to match the hardness, sound, and feel of gold), then electroplating on a heavy coating of gold. Such a bar would still feel and sound right and be only very slightly underweight, while costing less than $500 to produce in quantity. It would not pass x-ray fluorescence, and whether it passes a chemical test would depend on how thick the electroplating is. |
