What makes a good celadon? Being new to reduction glazing and not having
much opportunity to handle/see celadons first hand I am wondering what are
the qualities of a good celadon? It is hard to judge from just pictures. I
was very disappointed with the celadons from our firings - just a
transparent glossy glaze that was either green, amber or bluish, depending
on the glaze composition. What am I missing?

Dear Eva Gallagher,
You ask:
<having much opportunity to handle/see celadons first hand I am
wondering what are
the qualities of a good celadon? >>
Astounding clarity and intensity of hue seem to me to be two of the
main objectives. Robert Tichane explains the Science of doing this in
simple easily understandable terms.
You may have to prepare many samples of four basic ingredients; A
Felspar, some form of Silica, Some form of Calcium Carbonate, and a
Kaolin. Choose whichever sampling method you wish and get to work.
Should you wish to do this I certainly recommend you first read the
book by Robert Tichane, "Celadon Blues", ISBN 0-87341-667-8. This is
the Second Edition and has excellent full colour illustrations.
I wish you success in your venture.
Best regards,
Ivor Lewis.
Redhill,

Hi Eva,
Many cleadons have a special kind of transparency - they go light over
raised lines for instance - very effective for accentuating slip and carved
designs.
The best of them have a depth and transparency that is quite magical.
When you are in Toronto the Royal Ontario Museum has one of the best
Chinese Pottery collections in the world - you will see many celadon glazed
pots with carved designs.
Try brushing slip into a bowl - you will see how a shiny celadon glaze will
show every brush stroke.
