I wonder if your kilns is
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.
