every clay body you use will change the celedon.
every kaolin you use changes the celedon.
and, what iron you use, changes the celedon.
what temp you fire to, changes the celedon.
so, like shino, it all depends.
you will get, what you get.
if you do not like it..
change things.
a lot of things, one at a time.
it is a long slow process.

It is a funny thing with the names "celadon, shino,
temmoku... "
Its like saying "(insert skin color) people", or
"soup".
Such a broad range of variables that it almost doesn't
make sense to use them.
I suppose I should have addressed this differently,
If the clay, kaolin, and Iron are all the same,
what effects the color change in the glaze?
Application and firing are the obvious answers.
Since I do not have controll over the firing,
(yet... I will weasle my way into that so help me
moses)
the search becomes an accidemic one.
I will for sure throw a pot in the electric kiln,
see if blue green is the result.
My guess is the blue side of things.
Next will be to see if I can get the blue from
the original test to go green.
I don't know if you can get there from here
and then back again,
but it doesn't hurt to try.

My base glaze sometimes looks like a matt green celadon. Depends
how hot it gets and how much ash lands on it. Flyash creates shine.
The variation is important to me. This kind of glaze is great for
showing off zogan inlay beneath it. It is my teacher's standard
glaze.
Porcelain stone Amakusa is responsible for the
"frostiness." My current recipe is 3 parts wood ash, 2 parts ball
clay and 1 part Amakusa stone (Amakusa stone is used for Arita
porcelain clay body. You could try and substitute a slip from a
grolleg porcelain body.) Please let me know if you try this.
