Firing schedule with 4 firing cycles
- October 20, 2012 at 2:21 pm #9879
I’m so happy that I found this site!
I have a Sierra kiln 8″ that I use for PMC. I’m excited to try glass fusing in it, but the schedules that I’m finding all have more than 4 firing phases. My kiln only has 4, and I’m trying to get it right! I’m using 90 and 96 glass. My pendants are still coming out bumpy, and I’m not getting anything to slump! Any ideas? Thanks so much for the help.

Post your firing schedule and we might be able to help. For small pieces, four segments should be fine.

Ramp Goal temp. hold
R1 300 degrees 1150 degrees 30min.
R2 500 1475 15min.
R3 9999 1150 10 min.
R4 500 960 30min.
For Slumping a soap dish, I tried the following twice!
R1 400 1000 20min.
R2 400 1250 60min.
R3 9999 950 60min.
R4 400 100 0min.

I wonder if your kilns is firing cooler than you think. The slump schedule looks fine to me — I typically hold at 1100 on the way up, increase the temp slowly to 1225 or so, and often times my pieces are slumped by the time they hit the top temp (so 60 minutes is LONG). The fusing schedule has an unnecessary hold at 1150 on the way down (IMO), but that should not cause the pendants to be bumpy.

Thank you Dana for your help. I am going to keep tweaking the schedule a bit. It’s almost perfect on my pendants. Still can’t get a soap dish to slump, but I will eventually! Sure appreciate your help.

I have a tutorial on my web site that discusses and simplifies fusing for small pieces. many people get confused thinking the schedules posted for larger pieces are good for pendants. Not true. Size does matter.
