Glaze fire in electric kiln

[Jane56]

Hi

im new on here so you all might be hearing a lot from me as I have just started using my new Stutt kiln

only done bisque firing so far on an 04cone/slow speed. So far so good!

Do you do the glaze fire on medium speed- on the whole?

My personal answer to that question is. . . that depends. If I have just glazed the pots and  if they have waxed surfaces, or if there is high humidity as in mid Summer or Fall, I start off slower, then build once I see dull red heat in the kiln. My reasoning behind this is to let fumes from wax to dissipate, to allow the ware to dry slowly, not boiling out water that may cause some glaze flaws. Of course, as I said before this is personal opinion, others may think otherwise.

 

best,

Pres

I recommend using medium for everything unless you have large or thick pieces.

As you get more into the process of working with various materials, you'll find that  firing programs can also be selected based on the composition of the clay bodies and glazes, and the effects you may wish to avoid, or desire to produce.  I almost always use a slow glaze and a controlled cooling (^5-6 stoneware and porcelain), often with a preheat (though my last one went wonky because I programmed something wrong and missed it in the review!)

My skutt manual says to use medium speed for most purposes and so far it's done a good job.
