As you may know, I was on vacation in Maine. Just got in and not even unpacked, yet. Sadly, I found no rocks to share, but my cousin showed me this and I had to share. She found it some years ago near the shore. It even has one barnacle on it. It is very weathered, uncleaned, heavy for it's size (about 5 pounds) and a magnet sticks to it. It has a natural glaze, as pictured, on it's round side. It has a medium gray brown streak (which could be from weathering). I didn't have any tools with me to grind on it and didn't want to damage it. My cousin is taking it to the local university, but I wanted to see what y'all thought, too. What intrigues me is the natural glaze which looks melted and the cross hatching in the grooves. My husband and I think it is a meteorite and so does my cousin.

Looks like slag to me. That's the waste produced in refining metals such as iron.

I agree. With those flow lines, chances are it's slag. Most meteorites aren't going to have a streak, and I'm not seeing fusion crust (though that can erode away). Maine also has iron oxide concretions, but I'm thinking not that, either.
Interesting find, though.

I say slag as well. The crystal structure in iron meteorites will not show until chemically etched. Too rough a surface and vesicles also a give-a-way yo not being a meteorite. Very unique looking still and great crystal structure. Great find.

Ok I am going with a chunk of armour from the Mother ship. She blew a flux capicitor on the way to land to save the dinasaurs. Ergo the dinosaurs all died due to the failed rescue! The flow lines are due to the fact that Mother ships were grown from a organic metal producing bacteria on the home planet. Yall miss the simplest clues!!!

The Flux Capacitor blew out as it was over the 1.21 gigawatts!!! How could they be so foolish!!!

That exposed crystal pattern looks a bunch like that found in a meteorite, who knows what forces of nature that piece has seen over the last gazillion years ?
That piece isn't the whole nine yards, it is just a small chunk from the looks of it. With a flow pattern on one side and exposed crystal pattern on what was probably the inside , kinda maybe , could be !
Let us know when you find out.

Whatever it is, I like it. Very interesting specimen.

Thanks everyone! I have never seen the kind of slag everyone is referring to. I have only seen glass slag. My cousin will be talking with some people at the Bowdoin university, so we'll see. I'll keep the post updated.

I'll keep the post updated. There is a massive pile of it out a the Copper World smelter site in California. Also commonly used as railroad track base. Still that is the nicest piece I have ever seen. |

Scroll all the way to the bottom of this website. The last entry states that meteorites are strongly magnetic and slag is not. But then again, the meteorite does not look anything like the piece your cousin found.

I can't imagine how slag got to the location where it was found. |

Cool piece, let us know what your cousin finds out about it.

Most meteorites aren't going to have a streak Should have said that meteorites usually don't leave a brown or gray streak  Also, what's left in the slag all depends on the ore composition, what was being smelted, how efficient was the process and what was chipped off and thrown on the waste dumps. Some slag is little more than silica/glass (non-magnetic), other contains quite a bit of metal (often very magnetic). In smelting and other processing, metal deposits build up (and are cleaned out and often discarded) in chimneys, floors, iron oxide clinker forming during forging operations, etc. Maine has a history of shipbuilding and ironworking up and down the coast, so there is an alternative (especially given past practices for using waste heaps as fill). Meteorite is always a possibility, even if a remote one, so it will be interesting to hear what her uni contacts will have to say. |
