PostPosted: Feb 22, 2018 22:11    Post subject: Metallic Pliable Rock Found Metal Detecting???  

So me and my buddy we're metal detecting and I found this. Shows up as 25 cents on my detector, and silver on my buddy's detector. The piece I cut off is super Pliable and I can bend it with my fingers. Also, the metal can be scratched with my finger nail. And no, it is NOT magnetic. I tried two fairly powerful magnets with no response. Also, it weighs 1.1 lb, which is ridiculously heavy for the size.Does anyone have ANY idea what the heck I just found?

Maybe a melted anodized plastic or polycarbonate..

Have you tried a geiger counter?

Did you guys even read what Caleb wrote?

Very dense, electrically conductive, very soft, and sectile... That would probably indicate either lead, or an alloy of several metals, like plumbing solder. Other, more rare, metals could be possible too, like indium, but you're unlikely to find those.

funnily enough Alfredo, I can indeed read. Would be grateful for a little less administrator snark...

Caleb, I suspect that your "rock" is actually something man-made. It could be some sort of solder or welding material, or maybe even dried up metalic-based lubricant??? I suspect that we won't be able to help you further without doing some testing. But if I were you, I'd take it to a local geology department and ask around until you find someone willing to spend some time on your rock. Failing that, I would find a local rock club or rock shop where i could discuss this with someone who can examine the "rock" in person.

Good luck.

Sorry, Kevin, my apologies. I wasn't questioning whether you were literate, and not intending to be snarky. I just had the impression that people were only looking at the photo and not considering the physical properties Caleb had mentioned.

While not a definitive factor, you didn't mention if you found it on a man-made area [dump, near habitable areas or roads or construction vs. out in the middle of a forest/desert/mountain and away from human trafficed paths. I'm inclined to agree it is likely man-made of heavy/soft metals. If it is natural, you have certainly found something rather rare. Some more tests are in order. While most radioactive metals are not soft, I'd check it with a scintillation counter just to make sure.

If it serves for anything, I think same as Alfredo: a lump of lead soldering.
Other metals as indium fill characteristics, but I think that never have been found in such lumps...

If Caleb could measure its density, more info could be said.... (density relative to water is easy to do... Provided you can access at at least two decimals scale; better a 3 decimals scale)
And if you could measure the fusion temperature, even more info....

And as he says, looks as a man-made lump.....

With best wishes

It was found in alum Creek state park. It was on a walking path.

Exactly what kind of testing can I do to help this to be identified? Thanks a lot for everyone's response!

Btw guys, the piece j cut off isn't easily bended. It takes some elbow grease, but it does bend. Didn't want you thinking it was like putty.

Just an update. I am convinced this is a chunk of lead. My buddy had some lead bars in his shop, and they have the same properties. Look the same, melt at the same point, and give off the same reading on my metal director. Thanks a lot to everyone who helped me solve this!

Good for you!

If I am not mistaken, in the old days molten lead (or a lead-based alloy) was sometimes poured into joints in cast iron pipe to make them water-tight, and it is easily released from the pipe once the plumbing is dismantled. Perhaps this is where your lead came from.
