Want to melt old used galvanized nails and pour or shape into a large star mold.

My grandson recently tore down a very old building for the wood to build his first home.  I undertook the job of pulling hundreds of nails from the old lumber.  I want to melt the nails down and pour them into a mold of a Texas star.  Is it possible to melt the nails?  and if so; How? 

Galvanised nails are steel dipped in molten Zinc molten Zinc 800 to 1000 degrees, molten steel 28,000 to 30,000 degrees. I have found large pieces of Zinc in hot water tanks that were galvanised and cast parts of things that look like aluminium but are heavier than aluminium.
Zinc can be melted in a cast iron pot like tin and led.

Steel melts at an extremely high temperature. There are, however, ways to do it without spending a ridiculous amount of money. The best site, by far, that I have ever found for home forging is http://www.backyardmetalcasting.com/. There are many tips and tricks for casting steel inexpensively. The galvanization could be a problem, since it is essentially an impurity in the metal. Also, you will want excellent ventilation (outdoors is preferable) since galvanized metal is toxic when burned. I think you can accomplish your goal--Good Luck!
