Periodically I am overcome with the urge to put Zincolns in the oven. This is my latest batch, love the red!
Ya, you need to stop doing that. Most of those will probably end back up on Cointalk when some New Member thinks they've found something special!!
Does your oven go up to 790˚F? Better yet, 1665˚F? Zinc boils at a lower temperature than copper melts. You know what that means -- popcorn time!
Use the outdoor BBQ. Give them a spritz with WD-40 before you heat...lay them on a sheet of aluminum foil.
We used to do stuff to pennies too, when I was a kid. A friend of mine's father had a sand blaster, so that was something we'd do. Another was shooting them with bb and pellet guns. We would also shine tarnished pennies with pencil erasers, the ink pen erasers used to really get them shiny. I think the last thing we did was place them on the ground, step on them and then drag them across the cement. That was a magic trick to us, because doing so would change the color to shiny aluminum color, the part that scrapped against the cement. I guess the only thing left to do with pennies that may have never been done is to take a neatly stacked 50 pennies, bond them all together with liquid nails or gorilla glue and then slip them into a penny roller and then turn it into the bank. Who knows, that could be a new error from the mint.
Wow, you must have been a real joy to have around the neighborhood. Did you ring doorbells and clank mailboxes? LOL.
Actually if you put ONE coin in a container of water in the microwave it will boil merrily along. Two tend to start sparking...
In the "Silver Penny/Gold Penny" experiment, it used to call for the students to hold the zinc plated cent with forceps in a Bunsen burner flame. After the advent of Zincolns, the edge would just burst open and molten zinc would run out. I usually use 450 Degrees.
