smeltingPurityMembers of Makers Local 256 have been using a propane\waste-oil forge to smelt down computer heat sinks, aluminum cans, and various scrap aluminum into usable ingots for casting.  A friend of Makers Local borrowed one of the aluminum ingots to run through his spectral analyzer and determined that the smelting process has been yielding around 98% pure aluminum.

    I think so, but I’m not sure.
