Hey everybody,
I’ve been ordering my nitric acid through USA Labs and they’ve been alright, but just ran out of nitric halfway through a gold fill refine and was wondering if anyone knows any national physical locations where I might be able to get some
3 5oz bars from my first full batch in the silver cell. Tried a sulfuric acid bath to clean off the flux but still getting some off color spots. But happy with the results anyway. Waiting on some actual 5oz molds from pmcsupplies

This is a flat scale bracelet stamped Italy and IMO. It’s a very nice piece that is unfortunately too small for my wrist.

This bracelet has several tanzanite settings in between a pair of smaller diamond settings.
Willing to use a middleman if requested at buyers expense. Otherwise shipping from USPS included with purchase.
Poured my first bar from my silver cell. Seems like it picked up a bunch of flux. Any good ways to clean it up?
So I had a bar that I poured from silver contacts and wanted to refine it into purer silver to run through my silver cell. Ran it through a bunch of nitric boils until everything was dissolved. Added a bar of melted silver plated stuff to use up the rest of the free nitric before I added pure copper. It used up the nitric but then it turned into this thick milky blue substance. Is this silver chloride? I didn’t add any hydrofluoric acid so I don’t know how it could have formed
As the title says. Really just want to run one for fun but I’m wondering how long I can store “used” electrolyte before the silver and copper in it falls out of solution or if it will stay in solution for months?
Is there a way to estimate yield from a silver cell? Like I’ve been taking scrap silver I buy to a big name refiner and not trusting what their assay is coming out at and I wanted to set one up anyway for fun. But is there a way to tell when the silver in the anode basket is used up so I’m not just plating out the silver in the electrolyte or am I misunderstanding the process entirely?
Been buying sterling and selling to my local Elemetal refiner since they started taking silver again. The last two times the assay came in at 82.8% and 82.5%. The last time specifically I checked to make sure all the sterling was stamped with Italy 925. The fact they were exactly 10% below has me sketched out but don’t want to accuse them of anything unnecessarily
