What's in a name?
Concerning this business about Celadons - I had heard from
one of my pottery instructors that the word celadon derives
from the french who when Celadon ware was first being
discovered in france there was contemporary with the time a
popular play in which a character whose name was Celadon
wore green pants akin to te color of the celadon that was
being imported.? Anyone heard that story?
Of course there are pieces of pottery called Black Celadon -
I saw examples at an exhibit at the Metropolitan Museum in
New York in approximately 1990 or so - also in a book called
Korea's Pottery Heritage - published by Seoul International
Publishing House Volume two - there are examples referred to
as Black Celadon - 13th century Koryo ware - pp 79 - 80 -
81 - so does it refer to a shape, a type of glaze? a
period???
Does it matter ? The real question is does anyone have a
recipe for around cone 10 - or 9 that does the wonderful
pale blue really transparent pooling to deeper blues???
Thanks

Hi:

I've done a fair amount of work with sky blue celadons. I've figured out
some ways to make them work well. Do you want to know how this is done or
do you just want a recipe? I must say in all honesty that while I don't
mind sharing information and the occasional recipe (Several of my best were
published in the May 2002 Ceramics Monthly, including a blue celadon) I am
somewhat reluctant to pass on recipes to folks who don't participate on the
list. This may be an incorrect and unpopular stance but nonetheless,
that's how I feel.

Regardless of the above "soft rant", I will post seger formula and roadmaps
to the sky blue glazes if any of you want me to do that.

regards, Craig Martell Hopewell, Oregon

Hello Craig,

Please DO post your seger formula and any ruminations you will share
with us. This comes at a good time, as I'm interested in making a new
celadon, and have aquired a kaolin that's low in Titanium (Grolleg) with
that blue in mind.

Peace,

I think it was explained before. High potassium feldspar and
low titanium porcelain. Right? So far I have found neither.
The glaze I saw was transparent, and most "blue celadons"
have been described as translucent.
