[QUOTE="davsgold, post: 521378, member: 6570"] G'day jon_m The Mapp gas is fine but the flame torch that comes with it probably won't get hot enough as gold melts at 1060 deg C and that flame torch only get to " Flame temperature 1900F/1038C" I know this for a fact as a guy bought a pencil flame torch from bunnings (well two in fact) and had them in each side of his furnace and it was there for half an hour and it would not melt, changed to the blow torch type on the mapp gas bottles and the gold was melted in about 5 minutes. But hey you have it now and good luck, but if it is taking way long then just go to bunnings and get this one. I have used this type in dual into a small furnace and it worked.
