Not really. Toss into a crucible, wait until it has melted. In the event the drives use "standard" ceramics, this is only about 1600 C (slightly hotter than iron, slightly cooler than titanium) Even your standard propane blowtorch will hit upwards of that temperature in air. Granted, you'd do better using a 2-gas propane + oxygen (2800 C) or acetylene + oxygen (3100 C) setup. -- |_|O|_| Registered Linux user #585947 |_|_|O| Github: https://github.com/dpurgert |O|O|O| PGP: 05CA 9A50 3F2E 1335 4DC5 4AEE 8E11 DDF3 1279 A281
