Dear Rikki Gill,=20
You have piqued my inquisitive bump.
I am perplexed at the thought of a "Black Celadon" since the general =
definition of Celadon is of an Iron Solution glaze coloured pale green =
to blue with a fair degree of transparency and perhaps some opacity =
caused by bubble inclusions=20
Can you please define "Celadon" as you understand the term?
Best regards,
Ivor Lewis. Redhill, South Australia.

Goodness... as our elaborate porcelain threads have proven, sometomes a
name is all you have!
This reminds me off a Shino recipe we had floating around the U of O
campus for awhile-
Bubblegum Pink Shino
Makes me shutter.

Dear Rikki,
Having just read Dr Robert Tichane's work on Celadon Blues and seen
his illustrations both of original works and of his experimental
syntheses I would suggest that you are not working with a Celadon
Glaze in the sense that he describes.
From you description you have far more iron oxide than is necessary to
form a Celadon. My own perspective is that an iron bearing glaze which
becomes black and breaks to orange red and is brown when thin is a
Tenmoku (Japanese Nom) or Chien (Chinese Nom).
Having just seen the recipe you are using I would like to know how
this ever came to be called a Celadon, (which may be a question you
cannot answer). Even with 8 percent Red Iron Oxide the delicacy of the
blue-green range would be compromised, but it is good you find it a
pleasing surface and that it enriches your life.
Best regards,
Ivor Lewis
