Rock with Coal

I found this rock in an old dump pile that was with some coal. I think it is the remnants from coal being burned. Some remains are called clink but the pictures I find do not look like this. It sort of looks like lava.

Clink will look different depending on the type of coal, and thus the materials in it. That's certainly clink.
