how many passes through the mill do you make before annealing it again? or do you work it out by how far it has stretched? or how it feels?

I am constantly annealing, i dont even want to feel it stiffen up even the slightlest. Especially when working with silver on gold, Its really just a major safety precaution, and im probably wasting torch fuel but just the aame it makes me feel better. But i usually hit each side through the mill usually once, no more than 2 times each.x, 4 corners on a billet means 4 to a maximum of 8 passes and then anneal

How to do annealing for 14kt yellow gold bar of 4×8mm size thicknes oh 3mm.. pls help me out in this.. I was literally worried abt it.. purpose for this is to make plates... 0.35mm plate

Heat to cherry red and hold it there for 20 seconds. Quench red hot

Nice video. I have some questions. It looks like you stopped using flux and went striaght to heat. Is that correct? I have melted down a 14k white gold ring and am doing what you are doing. I do not know the alloy of the white, if it is nickel or palladium, but I am proceeding anyway as I will melt it down again when I am done. This is just for practice and to learn about white gold. I realize it will be different when I use an alloy that I know what has been put in it. Anyway, I have melted and formed an ingot. I did not add new gold to it. I am getting copper spots in the metal. I notice more of it when I quench it rather than letting it air cool on a steel table. I have filed them off and then rolled the metal as well as just left them thinking it is part of the alloy and will sink or rise anyway. However, I feel like this shouldn't be happening. Can you comment on this. I see your metal is just all black when you are done.

A boric acid alcoholic mix would stop most of that black oxides he had in the metal when done. In your case don’t quench it, with palladium you can quench as it doesn’t harden like a nickel based alloy would if you shock cool it with water. Your copper coloured spots would be the top layer having less gold and alloys in it when heating that outside layer most likely had the copper inside rise up. The boric acid coating before starting and air cool before pickle should clean that up. I think it’s most likely nickel zinc silver copper mix in your ring since palladium mix normally only has silver with it and gold. And the nickel shouldn’t be quenched ever that would shock harden the piece. I hope it helps trust me it’s a lot to learn I just alloyed my first piece of white gold yesterday came out nicely about to do my first annealing now.

@@mfdoom9125 What is in your alloy? Thanks for your post. It is helpful. My last go at it last night, I coated and coated it with flux and heated to just a slight red for 30 seconds and let it cool on steel. Some copper bits, but a lot less. Today I will try the alcohol borax mixture. I am practicing for a custom ring and we purchased nickel white and I am thinking of ordering some palladium instead. Let me know how your annealing goes!

@@anemonearts6216 you’ll need boric acid it’s slightly different than borax. They use it in tons of pest products you can get some from most pharmacy’s or Walmart. And fine powder is best to mix into the alcohol you dip it In and light it until the alcohol burns off leaving a coating of boric acid on it. I use borax sometimes as a protective flux but it leaves the black glass of the borax on the piece that comes right off with pickle

@@anemonearts6216 so far so good the first annealing looks like it went well I have it in the pickle now to remove alittle of the blackening before the second rolling through the mill. Same here using this to make a custom pendent for a custom cut Amethyst

@@anemonearts6216 also I used a nickel based as well for the client, they have no nickel allergy as I had her test for herself. It was alloy 974 from united, I would use palladium for the future myself too but the cost just makes it jaw dropping when the alloy costs as much as the gold base lol
