So found this strange rock but the inside is silver

[Rockhoppernc]

Was out hunting and found this strange rock!

 

[Rockhoppernc]

Has some weight to it, but the inside is as shinny as glass but more like silver, and very reflective!

 

[GatorBoy]

I think its either melted lead with patina on the outside or slag from processing iron

 

[Rockhoppernc]

Found it in the backyard of a house but found nothing other but a old shotgun shell

Is melted platinum very shinny inside? It is solid and no bubbles or inclusions. I have not washed it at all.

It's not lead or iron. They are not naturally shiny. Lead is never that shiny, even if you polish it. Would you happen to have a precise volume-measuring tool? If you do, we could determine the density and determine the material that way. Or you can take it to a metallurgist or geologist and get their opinions.

 

[ConceptualizedNetherlandr]

It is metal, right? I think lead would be shiny inside a freshly broken open previously melted blob. Probably same for silver or solder. Jolly balance would give you specific gravity. If it were pure that could be fairly definitive, but it would have to be a sample without the oxidized layer. If is lead it will not be shinny for long.

Hold a strong magnet to it, is it magnetic? Maybe slag or just maybe.. Meteorite?

Prob not meteorite. I agree with density/volume test. Do you have a graduated cylinder by chance? Could do a water displacement test for volume.

 

[Klclark3]

It looks like soldering dropped and gained a dirty coat.

 

[Rockhoppernc]

Well I cleaned the outside with hot water and cleaned up a little, the inside has not tarnished at all. Hung it from a string and used a rare earth magnet and no movement at all. I'm going to run down to a pawn shop and have it tested!!!

 

[Rockhoppernc]

Found a image of refined platinum that looks like it has the same shine. Who knows and crossing my fingers and toes!!!

 

[Diggin-N-Dumps]

cool find! what makes you automatically think its a precious metal? just curious. ive seen so many people deadset that they found melted silver clumps in there yard..amd 99% of the time its melted cans or lead..did the previous owners refine platnium on your property that you are aware of?

 

[Rockhoppernc]

Just hoping, I have been detecting for years and have never seen anything like it. I have crossed off I few ideas and should know something soon. Headed to the pawn shop to have it tested! Could be trash or treasure.

 

[Coldshuz]

What did you use to break it open?

 

[Plumbata]

The exposed break seems to have the fracture characteristics of Bismuth. I'm thinking it's something along the lines of the latter or Antimony or Cadmium, perhaps alloyed with other materials.

Be sure to let me/us know what you find out , but all the pawn shops I can think of would test it for gold or other precious metals (Platinum) . Witch is what you want it to be.

What I'm saying is they can tell you what it is not .
I would still like to know what exactly it is made of .
Possibly a Scrap yard (BIG ONE) can scan it and tell you what it is made of .

[Msbeepbeep]

Cool find! Hope it turns out to be platinum! Maybe somebody's jewelry melted.

 

[Idaho]

looks like oxidized slag to me.

Tin, Lead or Pot Metal(Zinc), most likely zinc.

 

[Rockhoppernc]

Pawn shop put it in a tester, it it zink!

 

[pat-tekker-cat]

Aww man.....
Well, guess you know where NOT to dig. now.

 

[Carolina Tom]

Missed it by this much...
