do you have a blueprint how to build this thing

[corpralj3]

Are you fucking serious with this guy using no gloves? There is no accidents with these types of temperatures, your fucking fingers/hand will be gone.

I wash my hands in molten tungsten, it's just a little warm. ;)

@1ToNJaB yes electric is cheaper then propane propane cost like 100 $ when your tank gets empty

@TheSilverGypsy Depends on the application. A ring, not worth it. Solar cells? Starting to look a lot more promising. Both use roughly the same amount of copper, depending on the amount of cells. By the way, I'm gonna post this here, since I'm too lazy to post it elsewhere. You can use a recipe for sugar glass to make salt "glass" for the solar panels. A lot of salt and a little water to melt it with. Pour it on your copper leads and let it cool.

@1ToNJaB

depends on how your useing the electricity, and how big your furnace is. A furnace this size useing a induction coils would cost alot less then propane considering the heat is generated by the metal it self via induction allowing it to reach melting point in a fraction of the time. Also take into account you never have to go buy/refill/recertify a canister with electrical methods.

$2.00 worth of electricity to melt 50 cents worth of copper.....ummmmm NO!

@corpralj3 this guy is absolutely right GO BUY SOME FUCKING KEVLAR GLOVES! There's no 2nd chance on accidents involving temperatures like that even with small quantities of molten metal.
