Greetings all. Posting here bc of wishful thinking. Looks like a meteorite but am almost certain it’s not.

Anyone confirm what this is?
Magnetite? Hematite?

Thoughts are appreciated

HAppy hunting.

Loads of vesicles (bubbles), so not a meteorite. An obviously melted appearance. Not natural, I think. Some folks will call it slag but I think it's furnace clinker... both industrial waste byproducts.

Pretty heavy. I think slag is quite light. No?

Furnace slag usually has a specific gravity (density relative to water) of around 3... about the same as non-vesicular basalts and rather higher than sedimentary rocks which are usually around 2.5, or igneous rocks such as granite at around 2.6

Slag can also have significant amounts of native metal, depending on its origin, that pushes up the specific gravity even more. Clinker may be around the same value but often has a lot more vesicles that can push the apparent specific gravity downwards (because the vesicles are just trapped gases that create a sponge-like structure).

As Red-Coat has posted, your item is not a meteorite. If you have an interest in meteorites, please pick up a few handbooks. Studying the websites of Certified Meteorite Laboratories is also very helpful in determining if your rock may be a meteorite.

Time for more coffee. Enjoy.
