Found in Chicago, Trying to identify- Black Glass
by Christine S
Hello! I'm having a hard time identifying this piece I found. I thought it would be a dark green or blue when put against light but no, it's straight up black. There are also some "ridges" on it, similar to what is found on white safety glass. When you look on the sides where it is chipped it is shiny black, no colors at all. Any advice would be appreciated! Found on Lake Michigan in Chicago.
