You make the call: I did some things out of order but will clarify. I wrote controls because I thought they might be Aluminum but some were not. Aluminum and iron dissolve in nitric acid.

unknown metal blob that kicked everything off:

1/2 reales found together:

.999silver that came with test kit, test right of it, turned dark red:

Ring stamped sterling, test to the right of ring:

Iron completely dissolved:

So there you have it folks. What I got on my hands is not Aluminum, some degree of silver in it. Of note, I tested a ring I thought was gold and it completely dissolved :(. Passed silver test and failed gold. Keep it mind I found most of these things in the same spot. Fire on a spanish ship is my guess...

So are you using 10k nitric acid test solution to test the gold?

Oh kool, nice testing example, now you're a Basement Chemist, thanks.

Of note the only metal I found that could mimic these tests is Cadmium. I think that would be pushing the boundaries a bit to believe that is what I dug up...

So the fire nugget melted aluminum cans tested positive for silver?

I forgot to tell you. The acid test is only good if you have experience using it.

Well to review the tests I have run:
1. Passed muriatic acid test.
2. Passed oxidation reduction test.
3. Passed bleach test.
4. Passed nitric acid test

The only test I know of left to run is electron spectrospcopy. I still know how to read the results; however, I don't have a electron-mass spectrospcopy machine available to me. If anybody works in an academic Organic chemistry lab and does have access I would be happy to send samples off to be run. That is the only way I know of to give a 100% definitive answer.

Without studying your pictures, did you find any melted blob that turned a brilliant red?

Only .999 turns bright red. Are you being serious or playing with me? I deserve to be played with...but come on...

Any melted silver is going to contain contaminants from the environment and prevent it from being a pure sample. Particles of sand, wood, etc...

Aluminum dissolves in nitric acid...period...amen...end of story...what else do you need to know? Look up negative tests for nitric acid online...

Ok I will study your tests but its very simple. With my solution 90% Silver turns brilliant red. I was assuming yours was the same. So what color is 90%?

OK what color is an American silver coin with your acid test? Mine is a bright red. And with each reduction in silver percentage turns a different color.


Its hard to see the colors on your photos. But Im trying. What color are the silver reales?

Ok thats good to know. With my test solution, aluminum and several other metals turn yellow.

I just want to add that I have no experience with your test solution but I was assuming it would be the same. I use the Nitric Acid/ Potassium Dichromate mixture and it changes color with different silver percentages. The 90% and over is brilliant read and there is no mistaking it.

How many different silver test solutions are in your kit?

I use the Schwerter's Testing Solution that I mix myself.

Schwerter's Testing Solution - Mix 1 gram of Potassium Dichromate with 22ml of concentrated Nitric acid and 8ml distilled water.

Pure silver turns bright red
Silver (Stirling Silver 92.5%) turns dark red
Silver (80%) turns brown
Silver (50%) turns green



If you have melted Spanish Reales, it should be bright red or dark red. As far as I recall, Aluminum turns yellow. Its been a while since I tested silver but I am sure Spanish or American coin silver will be brilliant or dark red according to purity.

Okay, I just ruined a silver eagle for no reason other then to prove something I already know. Insanity has its privileges. Seriously, I'm done with the haters. I've done everything asked if you don't agree then I really don't want your opinion anymore...

BTW: Here is a photo of my son with a stye in his eye...do you want to argue that with me as well?

sterling silver is bright red. I am not claiming the melted blobs are above .900. melted shipwreck silver takes on impurities...this is basic science. I'm not trying to pull rank or anything but do you have degrees in anything that qualifies you for this type of thing...because I do.
