Single firing stoneware, without glaze

[Chiv]

Hi all,

I use alot of medium grogged stoneware and keen to fire pieces only once, I don't intend to glaze these pieces either.
Previously I'd always done a bisque firing and then a glaze firing, but wondering now if I can keep to a single firing only, particularly as now there is no glazing...

I like to reach the highest temp of 1240 for the clay I use. Bar ensuring the clay is very dry before firing, could anyone advise an ideal kiln firing schedule?

Thoughts/advice/ previous experience really appreciated!

Run it up as you would for your normal bisque i.e.the same ramps  until I'd say

600°C then proceed as for your normal glaze firing ramps to goal temp/ cone.

Thanks @Babs! Assume this is to have a slow start/ avoid shock/sudden high temp - is this right?
Will def. give a go

Yes I would recommend doing it on low /slow

Couple of areas where clay can be sensitive to fast heating, also slow at start, or even candling if you not sure of moisture content  and clay thickness. Some folk hold somewhere around 700-800 °C to drive off xhemically bound water but if you havent had to up until now, I wouldn't start.

Let's know how you go,centainly save on energy and time.
