Since my last post, I had to add more small glass pieces to an edge that was very fragile, so this piece has already gone through its second firing. Remember the photo with the drawn 12" square and the arranged glass pieces? Well ... you can see by looking at it that there is an inch around the whole piece, so it is not an 11" square. Duh. A senior moment ... it is a 10" square.
Early this morning I sprayed it with a light coating of Clear Coat Overglaze. When you fire a broken bottle, there are spots that look like devitrification and the glaze helps.
Here's the piece with the spray.
The piece will slump today in this beautiful stainless steel mold. I ordered it many years ago and have never used it. It got sprayed with MR-97.
Here's the piece nestled in the mold on the kiln shelf. Keeping my fingers crossed!!
