Found black rock? In Indiana backyard

[Tyland]

I found this in my indiana backyard. This is a home I recently purchased. The property is scattered with junk so I assume this is of the same but would like to know if anyone thinks otherwise before I toss this find off as more junk.
Thank you in advance!

Welcome to TreasureNet! I don’t see it being an artifact of any type.

I believe it's a piece of slag.
