Ok thanks. I posted again before seeing your response.I believe you found a bit of Glass slag. Due to brown translucence and glassy appearance.
Obsidian. Volcanic glass.Dug this up in my yard in Minneapolis Minnesota. Next to fence post. A rock ID app says obsidian but that seems unlikely around here.
I'm just curious. I do find broken glass, but not colored glass and not this thick. I couldn't scratch it with metal... View attachment 2034885 View attachment 2034889 View attachment 2034890 View attachment 2034887
