Gold jewellery melting furnaces.

   There have recently been a number of small furnaces sold on Ebay that, it is claimed by their sellers, melt gold, this is something of a misnomer.   These furnaces barely reach the temperature to melt 'pure' gold and as gold, in many cases and specifically jewellery, has nickel as an alloy, it will not do the job properly.   To melt pure gold only takes a temperature of 1063°celsius (1946° Fahrenheit), to melt nickel takes a temperature of 1452°celsius (2646°fahrenheit).   A furnace that does not reach these temperatures will not melt all gold and will not melt white gold at all.   All white gold is alloyed with either nickel or palladium, which has a melting temperature of 1552°c (2825.6°f).

    If you're looking to melt scrap gold, watch out for misleading listings which tell you simply that a 'furnace melts gold' and bear the aforementioned in mind.   Ask questions and get positive answers or don't throw your money away.   Make sure there is a return policy in which there is no loss to you.

   Of the nine vendors selling similar machines that I have contacted with this information, two said they didn't know, two said they would change their listing accordingly (but have not), three declined to comment and one told me to stop stirring the s**t, presumably while they carry on ripping people off.

    As an update, I have had a reply from a trustworthy U.S. seller who confirms that their furnaces, which reach 1120°c (2048°f) will only melt 24 carat gold, if it's in small pieces, not nickel and not palladium.
