That would be true but I have the same rock and it isn't magnetic. If it was steel it would stick to the magnet I have been trying to figure out what this stone was for some time now it hard. I tried to scratch it with my fingernail and it didn't scratch I have had this rock since 96 and it has never chipped. If anyone has anymore info I would greatly appreciate the in put.

This is a natural mineral ore.  Possibly galena or hematite.  It is not a slag.

What you have is an iron formation with specular hematite.

Thanks a lot

This rock seems common because we have also found eleven samples resembling the one you are showing. It is not metallic slag from a smelting operation if you look it up...and i have found that it is not magnetic. Thanks for sharing I would like to know the answer too!!!

I can answer any general geology question (rocks, minerals, stratigraphy, geomorphology etc.). My expertise is in the geology of the Michigan Basin, PreCambrian, Paleozoic and Recent. I can answer questions concerning mining and petroleum exploration and production and the laws concerning those activities. I can also answer questions concerning stratigraphy of the Michigan Basin. I will also answer questions about mineral and rock collecting in the Basin. I won`t be able to answer many specific questions on hydrology, geophysics or geochemistry. I may be able to answer very general questions in those venues.
