Any change in your firing schedule may affect how the glazes turn out
(as if there weren't enough variables already). I always use the slow
glaze schedule on my kiln (different controller - no medium speed).
Since you have an order in there, I'd say fire it the same way as you
always do. The 1/2" pieces are more likely to cause issues during
the bisque processing, in my (very limited) experience.
If you're really nervous, pull your daughters ones out for the next
firing :) Good luck!

controller had E---3 showing (as I recall, it does Err for errors, so
no idea what E--- means, but either way, it came out fine).

I am getting prepared to start my kiln for a cone 6 glaze firing. I have
had great feedback. I am new so I don't have a lot of technical experience
as a potter and certainly not with kiln operation. Based on feedback, I am
taking that it is considered more standard to fire pieces at medium speed
(automatic protcocol). I am using a computer controlled KM818. The only
thing a little different is my daughter did some pieces that are closer to
1/2 inch--max. I want to use the automatic protocals, because I don't want
to experiment with these pieces. I have an order this time. :-) My
inclination is to medium fire it, but if I hear that slow is better, I will
switch it. Any feedback is great, esp. from those that are into cone 6
glazes. Thank you to those that have already helped. Take care for now.

"Medium" speed is fine, but once you reach red heat, 1200F, you can go
faster, then slowing down as you reach top temperature, then very slow
cooling from 1990F to 1600F.

Hi C,
Better learn how to program your controller - hold at 200F till no
more steam at your top spy hole - use a mirror or shiny metal with
both spys open to see any condensation - when no more water comes out
you can reprogram at 200F per hour.
The great thing about programming your own firing - you can slow cool
your glazes to get more interesting results from your glazes.
Let me know if you need more - RR
