Fool’s Gold – Using Ultrasound Technology to Combat Counterfeiting

Gizmag reports that banker’s and investors have recently discovered some gold bars containing tungsten using ultrasound technology.

The market news is quoted as saying,

Evidently all that glitters is not entirely gold. Just ask the many disappointed bankers and investors who have discovered some of their large gold bullion bars were ersatz – real gold on the outside, far less valuable tungsten on the inside.

Using non-invasive technology identical to that deployed in peering at developing fetuses, GE’s devices allow a quick and thorough examination of gold bars for flaws, bubbles and even different materials.
