These pieces are back in the kiln for a second firing commonly referred to as a Flip & Fire. The Flip & Fire technique is particularly handy when working with linear patterns or strip construction. After a first full fuse firing the glass that is against the kiln shelf will have sharper, cleaner lines then the side that is facing up. The shelf side will also have a matte finish and may have some texture from the kiln shelf. The piece can be flipped and slumped as is but it won’t have a shiny top. If the desired end result is to be shiny then a Flip & Fire before slumping the piece is necessary. In a Flip & Fire the piece is turned over so that the side that was against the kiln shelf is now facing up. It is then heated slowly, to just hot enough and long enough to shine up the glass.
For these pieces I also cold-worked the edges before the Flip & Fire. These are 9mm pieces that were dammed in the initial full fuse. I used strips of fiber paper around the perimeter that were slightly less than 9mm high; but I still had some needling around the edges. I should have made my fiber paper strips even shorter closer to 6mm. I had to grind the edges to clean up the rough areas. I also sandblast the side that will face up just to be sure there is no kiln wash or shelf paper residue anywhere.
The kiln is clicking away as I type this…. Hopefully all will be wonderful when I check in the morning!
