Why copper pans are great (and sometimes poisonous)

I can vouch for that Harold McGee book referenced toward the beginning. I have it on the shelf in my living room - though I'll admit that I've barely read more than a third of it. There's a LOT of science happening in there, and it's a dense read.

Adam explains the basics of heat conductivity, reactivity (leaching ions to make whipping egg whites easier), reactivity again (to pull sulfur out of the vapor distillate in alcohol distillation), malleability (peening the copper bowl), ductility (making copper whisks), reactivity another time (such as the health hazards of drinking acidic cocktails like mules from copper cups), and conductivity again (useful for making jams and candy).

And then he throws down the possibility of testing a pure silver pan...I want him to buy one, but I'm not going to support him to make that easier for him to do.
