I had a request for a broken wine bottle plate measuring 12" square through my Etsy shop. I have had two large cobalt bottles sitting for years waiting for this sale! My daughter gave them to me. So I got out a heavy plastic bag and a hammer and started breaking up the bottle. It didn't take long.
Here are the sparkling clean pieces ready to assemble into a square plate.
I drew a 12 inch square on thin fire shelf paper, and unfortunately the glass from the bottle didn't fill the square. So it will be an 11 inch square plate. You can't add glass from another bottle ... the glass may not be compatible and it might crack next week ... or in a few months. The piece is firing tonight, so I'll keep my fingers crossed that it looks ok in the morning. It will still need a second firing in a mold.
