Thanks for saying so! It suprised me aswell when I found out they were hot enough - I was so happy I didn't need a special torch for it. 10k melts at a higher temperature than silver, but 14k has a lower melting temp. Then 24k has a higher melting temp. The borax acts as a flux to get the heat even through all the metal, and also attracts impurities to make the metal purer. Although I started with 10k it will likely test higher on a nitric acid test, due to melting it with borax. Its quite neat, once everything is said and done - the borax has melted into a layer of glass.

24k melts at a higher temp than 14k And so does 10k? Now I am confused...
So potentially you could melt fine silver with a blow torch? Would you use borax for that too, do you think?

I know the melting points confused me too, thats why I thought I'd mention it lol. You definitely can melt fine silver with a blow torch! I dont think you would need borax, but it can help things along.
And again more good info on this. Thanks, maybe I will get into it one day!
