Thanks tracy. The Ellenville glass works was started in 1836 and there is a lot of that old glass in the stream near thie old factory. My wife had that piece for a long time and the few flakes i took off the cobble of glass DID not make her happy, i was going to make her a neckles out of a bigger spall but then i'd half to face the music all over again 😱 bye the way that glass works really nice with a hammer stone and pressure Retouch. thats how I did it anyway.
