Re: NEW! Celadon Show and Tell

by JBaymore » Aug 21st 10 11:10 pm

Celadon is traditionally a high fire (2350F+ 1240C+) feldspathinc glaze that is colored with iron oxide, fired in reduction, and which is anywhere from a pale ice blue to a deep jade gray-green. There are apocrophal anecdotes to the derivation of the name.... and I've seen a ton of these supposed stories..... but no one apparently knows that for sure.

Celadon certainly looks great on stoneware, but it is clearly at its best when fired onto a white colored or porcelain body.

NOTE: It is possible with modern ceramics technology to produce the celadon looking color and surfaces at lower firing temperatures and even without reduction firing using commercial glaze stain colorants. Lacking technical testing equipment most people would have a hard time telling these pieces from ones fired in the traditional manner.

Is this really "celadon". How many angels can dance on the head of a pin? :roll: It is not celadon in my book.... but if the color and look is all that is important... who is to really say.

best,

............john

I wouldn´t worry about that...ceramic is a very broad category and celadon is a type of glaze used on ceramics.

I love almost all celadons and marvel at the almost endless subtle variations on the theme. I'm particularly drawn to satin celadons, the less reflective surface allows for seeing into the glaze finish to appreciate its nuanced depth. Great topic, I look forward to seeing more examples.

Here is one of my satin glazed cups. This is a sweet little cup about 2oz. It feels double walled. I can't remember where I got it. If anyone has seen one like it, let me know. I'd love to get more. Thanks!

If you are really hot for that specific cup, maybe Lu Yuh Tea Emporium will order it for you - they sell some other items by that brand (Taiwanese).

I have a fantastic travel set in Celadon green (but not really Celadon of course) from them.

This book was a gift from the Mrs. and is rather technical to a layman, yet pretty basic to someone experienced like John. Since I would completely fall to the layman side, I had for the most part just skimmed through. But I am reading through especially as this topic leads ...

Thanks Brandon, I'll check it out!

Here are two of my favorite celadon cups. They are very small and so detailedl. A very unique dark olive color. They came from eBay last year.

I would like to only add to the topic that (as it is may be clar from nice John's description...) what is "celadon" depends on context. I maen that for example in Korea "celadon"means kind of pots or style and not glaze- clay(stoneware), several kinds of decoration and glaze,forms, fired in reduction. Of course now, due to globalization, it is changing...
