Starting a new batch

[Gwar]

Before and after prep..

 

[Gwar]

Getting ready

 

[Gwar]

Very odd, this is the first time the mud like leftover actually looks like silver.. strange

That is the residue after dissolution ? Or after runing it through electrolytic cell ?

 

[Gwar]

orvi, after dissolution and filtered / rinsed..

 

[Gwar]

I am going to make this batch silver shot, and then put it in the basket of the electrolytic cell I am constructing.

 

[Gwar]

Almost dry..

 

[Gwar]

Pretty much everything, I did add a few grams to make sure it was a good pour, and I did have a little left over in the crucible

 

[orvi]

Strange. It look pretty much like very fine silver cement. Did you boiled the reaction ? Did you make sure you added enough nitric ?
Thing is, that when some other noble metals are alloyed with say silver, and you etch away just silver with nitric, residues aren´t shiny - but often greyish/blackish/brownish coloured.

I will wash the undissolved solids from AgNO3, and then try AR - if it could get it to the solution. If it is just some junk, or it has some values in it

 

[Gwar]

It is strange, this is only the second time I have used Canadian coins, the last time the 13 Canadian dollars I used left behind a inner round piece of metal, exactly identical to what we see here, it's like the coins are made different than the U.S. Mercury / Roosevelt dimes that actually leave no trace whatsoever after the Nitric and Distilled mix..

 

[AMS-Pro]

You have the dried sludge as sludge right, and not that bar you showed?

 

[Gwar]

AMS-Pro, this is what was dried from the coins, and also what was used to pour the bar shown

 

[AMS-Pro]

So for clarity, the bar is made from the sludge?

 

[Gwar]

Yes.. I rinsed about (9) nine times to get the color clear and then dried the material

 

[AMS-Pro]

Place the bar in your fume box and turn the fan on. Take a pipette, and drop a few drops (1 or 2) onto the surface of the bar. If turns black then it still has silver content. If it however bubbles green, it's probably nickle silver which has no actual silver content, or if it does, it's very little.

 

[Gwar]

My plan is to remelt the bar tonight and make semi silver shot for the Anode and start up the cell..

 

[Gwar]

Ams-Pro, what chemical should I use for this test ?

 

[AMS-Pro]

Undiluted nitric acid.

 

[AMS-Pro]

Also, I'm on my phone at the moment, and working, so I apologize for the short responses.

 

[Gwar]

OK, I did as you specified..
