Here’s an interesting phenomenon Not sure where it was found. This little nugget has all kinds of surface colors, crystal growth & a dense weight. cut to see the inside Metal! Not magnetic. Flakes out with a knife. Pretty sure it not lead. Didn’t seem soft enough. I figured sort sort pot metal. Could it be some kind of industrial slag? Thanks for looking Ed

Could be zinc. It looks like the same corrosion that happened to the zinc plates attached to the pressure hull on nuke submarines.

that interesting Don! We did have a Geiger counter & there was no clicking
does zinc naturally corrode or does it need catalyst? & what kind makes crystals & colors ?
sometime ya just never know what your cutting into

Any natural salts and ground water will corrode zinc. The corrosion is mostly in flat, flaky plates or powder, but I have seen needles on it. One of my jobs used to be crawling between the outer and pressure hulls on subs, and changing out the zinc plates. Don

Don, I remember seeing the badly corroded zinc plates when we were in drydock getting the reactor refuled. I don't remember seeing anyone changing them, though I'm sure they were changed before we went back to sea. Bob

could it be pyrite? It looks sorta like the stuff I find around Jerome in the Mingus mountains. Polish it up. if it turns the water black when cabbing, and takes aon a mirror shine, it just may be pyrite.

Lead ore or, Galena ? isn't soft, it's hard and will flake, but it never has a patina like your sample. Surface colors sound Pyrite as lead is brite shiny silver.

Hey Bob, we had to wear a harness and rope to change the zincs. They were welded in with a tab on each end. We ground the top tab loose, attached a line to it, and then had to grind the bottom tab loose. They'd lower a welding stinger and new zinc down to us, and we'd weld the new ones in. The real fun was doing the zincs around the torpedo tubes. We had to go in through the outer torpedo door, and hope someone on the sub didn't close the door on us. Don

It does look like galena to me and I have seen plenty of it with that white coating of what is usually limestone around southeastern kansas. without having it in hand though it's a hard id.

Knowing where it was found would help narrow it down Perhaps, I'll get a better analysis of it Thanks agrin ed

One guy said after I cut it: meteor ! and I’m like: ‘I just cut off $10,000.00 !! ‘ Definately not a meteorite...it wouldn't have a stoney crust if it was a meteorite...so no need to worry about that....

Not a problem In all my many, many years of rockhounding, I've only ever found one small meteorite that was verified as being the real macoy...not something you find every day... Glad you enjoyed it, I love jade and I'm lucky to live in about the best place in the world to go hunting for it...I'm a third generation jade hunter n my family and I'm training the fourth generation now...
