Black Sea Glass Identification?

(Ocean Isle Beach, NC)



I found this piece of glass on a beach on the west coast of Ireland.

It's so dark, I can't see light through it and appears to be black.

Can you help with any information on this piece like what it came from or how old?

Have you tried shining a bright light through it? A phone flashlight works really well.
