Found a heavy metal-like rock today

Miner are you sure it's a metal; does it conduct

Does it chip, is it at all glassy

Not glassy at all, it has a dull grey/blackish exterior, except the exposed part which is shiny silver. I dropped it in a pot of hot water, and it's still holding heat very well a few minutes later. No chipping at all, but when I dropped it in the ceramic pot it left a silver streak where it hit the bottom.

Thanks Miner that might help
Oss, Man, where are you

Here are some clearer pictures if this helps at all.

Slag from a furnace somewhere maybe? Is it magnetic?

It's not magnetic, there were slag rocks mixed into the driveway though.

It's black enough to be hematite, though hematite will normally display a metallic luster usually calle adamantine.

no he said it left a silver "streak" on the porcelain.
Id do a specific gravity test (you can find instructions on the internet Im sure). Then, after that, if it has a specific gravity of , around 9,5 to 10. 5, its a mineraloid mix with silver in it. If its like 10.5 and up, its an amalgam with silver and probably something heavier.
The silverish streak was what caught my attention.
Roger-hematite gives a reddish streak. NOW, it could be a magnetite or titanite pebble. Magnetite gives a blackish streak.

Specific gravity will tell us. Dont go screwin around with any liquids on metals, all youll do is mess up what could be a nice specimen

RULE 1... Try not to screw up your specimen with very destructive tests.
You can hurt yourself or mess up a specimen. Be very very careful , it has some nice fetures.
I first thought it was a desert varnish bit the streak and the weight, changed my mind.

Good luck

I forgot about that. I saw black, heavy, and metallic and went for the easy one.

Ill ask him if he can make a mark on paper with it?

I did the specific gravity test, 6.28 and 6.32 was the result of two different tests. I cannot mark on paper with the rock. Maybe it was just that bowl I used, but I tried rubbing it on another cup, and no mark came up.

well, it could be the chromite group with iron OR, and that worries me. It could be uraninite cause the sp gr is right in the mid of a mixture with other U minerals and it looks more like pitchblende than chrome.
Get a UV light (short wave light which are usually found in those money testing lights that stores use). If its a uranium base itll flouresce a yellowish (weak but there).
If it is a uraninite. (and Id assume it is until we find out it isnt) Keep it wrappd in some aluminum foil (Two sheets of heavy duty will stop alpha and reduce
beta). Then your problem is what to do with it. Id give it to a mineralogy dept at a local University or a museum that has a geo curator. These people are familiar with handling and disposal protocols. I wouldnt keep it. If its chrome no biggy.

I went to walmart and got a UV light, it's not glowing any that I can tell at all.

I thought it might be a smoothed piece if anthracite, but the specific gravity seems too high for that.

I like some heavy metal, but a lot of it just sounds like undifferentiated noise to me. It certainly does qualify as rock music, though.

Thanks, sure does look metallic doesn't it Miner

But Man isn't magnetite magnetic

I've forgotten so much

your right, I didnt see that he said it wasnt magnetic until after I posted.

So, basically this is iron and chromite mixed?

Thanks.
