Getting there

[MCB0513]

I'm getting there had all kinds of issues from crusible issue to to much flux to all kinds of stuff but it is coming together

Good to hear! Congrats. Is this continuing on your introduction thread?

Yes so when I try the bars it is not getting solid all the way through. What could that be not enough gold or im lacking something else?

Not enough information.
Is it the "nuggets" in your introductory?
How do you treat them before smelting and what is your flux.
That would be a start I guess.

Not sure what you mean with trying the bars.
If you're smelting, a cone mold will collect the metal in the bottom leaving flux on top.

So I wash everything and I am just processing the small stuff at the moment all the real fine gold that could be the reason. The way I was told though is that the real fine stuff makes bars to. Maybe I'm just not putting enough. I am using Chapman flux. Thanks for commenting and helping I appreciate it!

So I don't have a cone I am just smelting and pouring into a mold. Is that not correct?

It works but a cone mold is better as the metal collects in a smallish point (cone shaped button)
But how do you treat it?
Milling it well and mixing with the flux?
Do you use collector metal?

If you put the mold on a slanted surface you create a kind of cone in the corner.

As said a collector metal like lead or bismuth helps to gather the precious and base metals in the bottom. Your flux needs to be right for the material you're smelting. It needs to be fluid enough and have some convection in the crucible so all the material passes the pool of metal in the bottom.
Then you can pour it in a pointy mold and cupel it.
Did you melt concentrate or rocks? And how much?

Edited for spelling.

Thinking about it, bismuth is used for cupelling. I'm not sure if it works as a collector metal.

No concrete or rocks it's like a black oily film. I think I know what might have did it I was using a iron rod to stur do you think that had a effect on it?

Yes I mixed the flux in before I smelted. What kind of collector metal?

The question was if you smelted rocks or concentrate, (not concrete).
So did you smelt an oily black film??

Either Copper in small particles or best might be Lead Oxide (Litharge) and some Carbon source like ordinary flour.
Then mix it thoroughly before smelting.

Ok I will definitely try that . Thanks a lot I really appreciate it I have been working really hard to make this happen and it keeps winning lol.

The only thing black I used was the Chapman flux that's it. I didn't roast the gold before I smelted it and that iron strur rid I was using that's the only thing.
