✅ SOLVED What is this rock?

[SCUFFLES]

I found this rock. What is it?

 

[Mud Hut]

Are you sure it's a rock and not some sort of composite or resin?

 

[ConceptualizedNetherlandr]

Why do you think it is a rock?

 

[SCUFFLES]

At first I also thought that it might be something else but after checking it more carefully I’m pretty sure it’s a rock but I could be wrong.

 

[Limitool]

Well if it is a rock then someone did some machining on it playing around. How and where did you find it...?

I found it yesterday by the Ottawa River in Gatineau Quebec Canada.

Looks like a broken and water-worn piece of moulded tiling made from some sort of composite material to me.

WHY... do you believe it is rock or a stone..? Because of it's overall weight..? Have you tried to drill a hole into it to see if you can easily...?

 

[russau]

I'd take it to the closest University & have it examined for the make up of it's material ! Then you could make a educated guess at what it is or was !

I don’t know if it’s a rock or not but why does it have those lines on it? I don’t want to drill a hole in it because I don’t want to damage it.

The lines.... Because somebody machined them into it. Which leads to it being composite material not rock. Most composite material will easily drill.

Are the lines bumps or divots? Hard to tell...

Agree with Redcoat that it appears like a piece of manmade material, likely made in a mold, not machined. Probably fired clay which would be hard and have a texture like fine-grained rock.

I also think it looks like a piece of man-made tile.
A water-worn piece of a bull nose tile.

It could be a piece of road tar before grout was added. The machine used for laying road tar could have left such an impression. Tar, once hardened, is softer than most rocks, but not by much. Take a torch to the corner. If it softens there's your answer. And that shouldn't damage it either.

Thank You! That should be the right answer. This thread is SOLVED.
