Melting up gold and making a bangle - By Mobeus Jewellers

[skrotomsak4]

when you melt the gold say you have 24 k .999 gold when you melt it does anything burn away leaving you with less weight obviously impurities will burn away but i mean like will the gold be reduced?

@skrotomsak4 golds boiling temperature is higher then its melting temperature, now unless youre going to get it to a 2856degrees celsius. you wont have to worry about boiling off gold. and pure gold (24k) is not good to use for jewellery due to its softness

Hi, I am also a gold smith, I want to know what is the KARAT of your gold?

does borax remove impurities from gold

[Mikeandwendy74]

Was that a charcoal block you melted the gold on with cut grooves?

@Mikeandwendy74 Hi yes it is a charcoal block.

[aieeejo]

Do you ever separate out the impurities/non-gold metals? If so, how?

[8mobeus8]

@aieeejo unless you use 24ct gold there will always be other metals in the gold, any impurities are burnt away in the melt down.

just like bbq

[8mobeus8]

sulphuric acid diluted 7 parts with water... dont pour the water onto the acid first.. it will explode.. it will crack off but could damage your rollers and it will embed into the gold

[boochieboy814]

How do you clean off the borax glass before you roll it???,,,,or does it just crack off when rolling?

[atlantisak]

I'm going to be starting metalworking soon and have been doing a lot of research when I came across your video here. I'm just wondering...what is the white foam that is being sprayed/dusted onto the metal as your'e melting it?

[8mobeus8]

@atlantisak Borax powder, its flux to make the metal melt together smoothly. I only know precious metals need flux other types of metals might not?
