raking rage
Three successful raking......until....latest.....three big bubbles leaving big holes. Why? First, put down thin fire paper....the pieces of clear glass (I did not use a solid piece but have done this before with no problems) to cover shelf, then lined up glass rods and BE strips of glass and fired away using Patty Grey's combing schedule. Have always gotten good results following the same pattern but this time big bubbles and I do not understand why?
Help appreciated...........

raking
The bubbles or holes inch wide were there before I raked. Raked through them and managed to close them but the fire paper came through..now looks like devit. Used the same method before (large pieces of clear on bottom and rods on top) and this never happened?

Glass thinner than 1/4" is particluarly prone to killer bubbles. Thicker is better. 1700 is a very unforgiving temp for glass. Everything must be just so for it to survive the experience.
