Does melting gold purify it?

Does melting the gold purify it? Yes. In fact, melting is the oldest method to purify gold with fire. However, since the melting temperature of gold is 1064 degrees centigrade, melting at this point leads to high risks of severe burns.

Will gold jewelry melt in a house fire?

Because gold melts at around 1800 degrees Fahrenheit (depending on the karatage), and most house fires burn at less than 1200 degrees, it is rare that gold jewelry will melt beyond repair in the event of a house fire. … This means that, when everything else is lost, jewelry can often be salvaged.
