[QUOTE="thedigger, post: 234086, member: 2037"] Put it in some battery acid(Sulphic acid) that should dissolve the borax. It looks to me that you are using far to much borax,you only sprinkle the borax on the gold when it is bright colour,just before it is ready to melt. Another cause that can lead to the problem,is if the gold is dirty and there is quartz in it. Also if you put the acetylene flame on the gold it can blacken your gold. I refine gold and I use a electric oven,so if you aim to melt your gold in the future you will find it easier to use one,you can find them on gumtree or Ebay secondhand at a good price,a small unit,enough to just fit he crucible in,one that that has temp to 1150c.you will get a nice clean melt.
