i was thinking about this the otehr day...
2000 F to melt copper...
about 780 degrees F to melt zinc..
the pennies past 1982 are made of 97.5 percent zinc and 2.5 percent copper. Copper and zinc have similar heat indexes... Pennies before 1982 are made otu of 95 percent copper and 5 percent zinc..
I am hopefully going to either get like 300 newer pennies and melt them in my fireplce ( i have done it before) and pour the result into a clay.
Clay or ceramic is what they use for casting copper and other hot metals. But if this goes through i can make a nice water block for around 3 dollars
