Annapoorna,
Regarding single-firing, you can do that with
virtually any surface treatment...including the
celadon and chun. You just need to fire slowly enough
in the early stages of the firing to burn out the
organics from the clay and to decompose any carbonate
present. I single-fire at a bisque schedule until the
end of a normal bisque firing, then complete firing at
a glaze schedule...more or less...and it works fine.
The result, of course, is a longer firing. :-(
Good firing,
Dave Finkelnburg

hello
i have been reading the posts everyday first thing in the morning 5 am.
It is highly educational and i have so far managed to avoid some of the
pitfalls of a begginer potter.
thanky you all.
now for the questions
i am trying my hand at firing some celadons.(i know it is ambitious but just
fullfilling one of my dreams)
The big question is i have two clay bodies that i have made from scratch,one
fires grey in reduction and one fires white.
i want a blue celadon so do i use the white fired claybody for a blue
celadon.
the second question is i am also interested in chun glaze so my question is
the same which clay body for a jun glaze.
second series of questionns
can i single fire them ??
thanking you in advance,

Hello Annapoorna,
If you want blue celadons, be careful to keep the titanium content as
low as possible. Titanium causes them to be green. It can come from
the clay body too, so use the clay that has the least titanium
content. I would try both. I'm not sure if the same applies to chun.
It's also recommended to use feldspar in the glaze that is as high in
K2O (potash) as possible.
Single fire glazes that I've found to work well always have some clay
in the recipe, at least 10%.
Good glazing,
