| 449128 | 2006-04-24 12:01:00 | It's a tad expensive.... Like about $750/kg at a rough guess. |

| 449129 | 2006-04-24 12:26:00 | And a tad maleable. Silver melts at 961 degrees, carbon steel between 1353 - 1464 degrees. | Winston001 (3612) | ||
| 449130 | 2006-04-24 12:47:00 | Still have a 1.0 kg .9999 pure silver ingot here, bought as "an investment" about 20 years ago. Worth almost as much now as I paid for it. At only 961°C melting it would not be safe as a pot in this house ... |

| 449132 | 2006-04-24 23:54:00 | I take the vow of silence on that one. | godfather (25) | ||
| 449133 | 2006-04-24 23:58:00 | Fear of incriminating yourself Goddie....... :D So Mrs Goddie is the boss in your house then???? :p beetle :lol: |

| 449134 | 2006-04-26 02:38:00 | It's a good conductor of electricity too . In the atomic bomb project, they needed some powerful electromagnets and went to the US Treasury for some silver to make the winding wire . The Treasury was quite happy about this . . . but they gasped when they discovered how much silver was wanted : tons . Gold and server were traditional for royal tableware (bacause of the shinyness, and cost) . Napolean was given an aluminium fork once . . . that was because aluminium was more expensive than platinum when it was first made . |

| 449135 | 2006-04-26 03:46:00 | Nowadays you can use HTS (high-temp superconductors) for winding wire in high power electromagnets. In fact, a NZer discovered them (Jeff Tallon), and holds the patents to the Bi-2223 superconducting material - currently the only type able to be drawn into wires effectively. | somebody (208) | ||
| 449136 | 2006-04-26 03:52:00 | But not 60+ years ago . ;) Then, if you wanted a powerful magnet you used lots of steel core and lots of wire, and many kilowatts of power (and usually lots of water to get rid of the heat . . . the uranium enrichment plants were built beside rivers for a reason) . Superconductors make terrible cooking utensils . |
