Do you have a certificate of authenticity? If so why melt the flakes down? You would lose money that way (not that it is much we are talking about anyway, but still). If you don't have a certificate than how do you know it is 24k? Anyway melting gold is easy if you have the proper equipment. Just put your gold in a clean pre-glazed crucible and fire up the torch making sure you have a neutral flame maybe adding a pinch of borax flux. Be careful not to blow the gold out of the crucible with the flame. After it is all melted then let it cool a bit and pluck the bead out of the crucible with tweezers and put it in some cold water.
