It worked fine. I did use a lid over the top and welding goggles on my eyes. I melted some copper wire and then added some zinc to the molten copper. The zinc flared up with white smoke. When it all cooled i had a piece of bronze about the size of a nickel, more or less. Had to cease operation of it after my father received the months electric bill. The resistor was probably around 6 Ohms or so and therefore the furnace was drawing close to 20 amps.

Such a device is what a small time refiner and reclaimer of Platinum Group Metals could definitely use with repeated warning on eye protection. The new masks would take care of that danger as long as one does not get forgetful. Getting "sandeyes" from welding arcs is bad enough but CA is even worse that that oor even direct solar viewing. Thank you for that artical I believe one named Nicola Tesla came up with the original idea way back when and for the most part is no longer common knowledge but it soon will be again now that precious metals are going upwards at a phenominal rate because the world is on the verge of return to metal backed currencies and the so called fiat or unback ones that we have been forced to accept since 1913 when the FED came into being along with all the other central banks of this greedy world.

He ended up burning his retinas or something. He basically had to lie in nearly complete darkness for a couple of days until they healed. He said that any light at all was just a horrible stabbing pain. Glad it wasn't me, though no telling what damage I did myself. I DID this with a friend several years ago.
