Entering Firing Speed
With Ceramics there are certain critical temperature ranges where it is important to slow down the firing
rate. Cone Fire Mode takes care of most of this for you. All you have to do is select one of three firing
speeds; Slow, Medium or Fast.
Slow is generally for your bisque firing (clay is dried but has not yet been
fired). Medium is recommended for your glaze firing. All the water should
be completely out of the piece and most of the organics have burned out
so you can fire a bit faster. If you have an unusually large or thick piece
you may want stick with Slow just to be safe. Fast is only recommended for
Decals and Lusters.
Selecting a Hold Time
When you enter a hold time, you are telling the kiln to maintain the peak tem-
perature for the amount of time you have entered. A 5 minute hold time can allow
the kiln time to even out and make sure all the glazes are flowing nice. If you
Hold too long, you start to affect the amount of heatwork. Just as you wouldn’t
want to cook food too long, don’t enter too long of a hold time. Remember, the
numbers to the left of the decimal represents hours and everything to the right of
the decimal represents minutes.
