✅ SOLVED Aluminium stones?

[MrBeep]

Hello all! When I started with MD, I started finding these strange objects on my property (I think it could be aluminum, but I'm not sure). At the time of the photo, I had found only three, but since then, I have been collecting dozens of these objects.
They are deep and obviously full of mud and grime, but they are easily cleaned.
It looks like remnants of molten metal. I have no way of knowing what metal it is or what its origin is, since in this area there are no heavy industries... only fields and forests.
Could some of you guys help me IDing it?

Thanks!!

I’d say clinkers from where someone had a burn pile and there was something made of aluminum in it That melted into a glob. Very common on beaches, river banks and out in the boonies party spots.
