My friend found a rock while doing some excavating around his old farm house(over 100 yrs old)?
He says it is very heavy, could it be platinum?sorry about spelling. in ashtabula,ohio!!and its hard!shiny looks to have broken when discing the dirt not cut!
I was told posibly pionite?it isn`t magnetic.no rust,looks like it may have been forged at sometime,dolimite?
it is also very hard,not lead!or soft metal!
There’s not many platinum mines in Ohio, so I would probably rule that out.
You can do a couple of things:
First – put a magnet on it. Does it stick? Then you’ve got a lump of steel or iron of some sort. The scrap price of steel is pretty high, but unless you’ve got a huge piece, it’s probably not worth a whole lot.
Or…
Wwash off all dirt, etc. Then compute the specific gravity – to do that, you weigh it on a metric scale, and record the weight. Next, place it in a graduated cylinder partially filled with water. Subtract the starting water level from the ending water level to get the volume of the rock. Divide the volume by the weight to get the SG. Compare this to different kinds of rock, metal, etc, to get an idea of what it is. This is just basic physical science.
Or….
go to your local high school, community college, state college, etc, and ask to talk to a teacher or professor that teaches geology, and have it evaluated. They’ll probably be able to identify it fairly quickly.
