System 96 Firing Schedule

[saracen]

Hi, I bought a new kiln recently from Evenheat and downloaded from here General Purpose Firing Scedules. A number of square pieces I fired are suffering from “Dog Boning”, where the sides are drawn in a little. I’ve heard that sometimes that System 96 is not always the same thickness throughout which might be part of the reason. Can anyone suggest what I can change in the Scedule to prevent this happening?

Are you using two layers of glass? What is your firing schedule?

While I have heard people say that System 96 has uneven thickness, I would think for the average glass fuser this is a non-issue. I use 96 exclusively, and if I have any issues with the glass, it is more likely coming from my “technique” that anything to do with the glass itself!

Hi Dana, yes I am using 2 pieces of glass and I tried the generic schedule I downloaded from here, adjusting the anneal hold for System 96 as suggested.

The schedule is:

300>900 hold 15

500>1100

100>1250 hold 30

9999>1475 hold 10

9999>950 hold 45

100>800

200>700

400>100

I can’t recall this problem in my old kiln, or maybe it’s just that my eye is keener now. Any suggestions? Would be grateful to be pointed in the right direction..

All kilns fire a bit differently — this one may be firing hotter than your older kiln. Try reducing the temp 25 degrees, observe, reduce more if necessary.

In my kilns, 1475 is definitely at the top end of full fuse.
