But why not use a huge piece of expensive equipment; commonly referred to as an oven. It can double to roast your Thanksgiving turkey, and lots more. Anyways, the reasoning goes something like this: the UV light is just some extra energy you're giving to release trapped electrons. So why not use some other form of energy, like heat? This has actually been successfully done, although I can't remember the temperature or time. I think it was half an hour at 300 degrees. Start at a low temperature and work up to it by trial and error. One extra note, this works only for ceramic packages. Plastic ones would probably melt and be difficult to plug back into the sockets.
