Who knows their rocks? Pic

So we're painting rocks and got these rocks at Lowes but they seem to have some oil content and won't take paint or urethane well without chipping off. Anyone know what kind of rock it is? Other than a love stone.....

Is it real heavy? We have a lot of iron around here that looks like that

Help me understand? You went to the store and bought some rocks?? All those rocks I picked in our fields and did not know to sell....

Oil shale ?

My first thought was why buy plain rocks too.

If I had to guess though, I'd say some sort of basalt...

I am rich ...... Had a bumper rock crop this year in my garden . I can sell you a ton or five that will be paintable guaranteed or your money back ..... its like strawberries . You can pick your own. Fun for the whole family

Id say shale or coal

^^^^
My first thought also. How hard is it? Will it scratch easily with a nail? If not, basalt might be your answer. As to the oily surface, maybe they treated them with oil or wax to make them a little glossy?? Crack one open and post a picture.

Soapstone?

i would think shale

Believe it or not, there are parts of the country where rocks are pretty rare!
But sorry, Gary, I can't tell much about it.

Theres not a single rock on my whole property. Nope, they're all married with big families....

A few years back they started rip-rapping the shores in front of all the expensive lake homes to prevent erosion. Excavators and landscapers started buying up all the rock piles the local farmers had been saving for generations. Once the farmers got wise to what was going on, prices of rocks went up considerably!

Went out and picked these up a few weeks ago. They don’t need any paint.

Here's a broken one.
My niece and her hubby took some boulders from the farm to the city and put them in their front lawn. It raised the assessed value by 20k!

I know that rock, I seen it in the movie Knowing with Nickell's Cage they were all over the place

You guys are starting to worry me First the JP thread and now this
Benson have you and Sprung had the vaccine perchance??

His name is Stoney

No! That is Pebble!

Staying with basalt...

The broken one's grain looks too soft to be basalt but maybe. I snag the photos and send them to an old geologist I know, along with the detail that paint doesn't stay on it well. A person should be able to paint basalt.

I am going to say basalt or diabase

INDIAN LOVE ROCK !!!!

Non, I agree he should be able to paint basalt, but I believe these were store-bought and treated with some wax or oil...Please do send the pics out to someone you know as now I am interested in what it is!!

Do you offer free shipping?

I think they were treated myself. From Home Depot in a 30# bag.

It's a rock from a quarry where the loader has a hydraulic leak. Pre-treated waterproof rocks, they should be marking up the price more.
