Celadon was a type of pottery glaze that was developed around the same time as the fine porcelain china most of us are familiar with.
Celadon glaze refers to a family of usually partly transparent but coloured glazes, many with pronounced (and sometimes accentuated) "crackle", or tiny cracks in the glaze produced in a wide variety of colours, generally used on stoneware or porcelain pottery bodies.
The celadon kilns operated mainly in the north of China whilst the porcelain pottery industry developed mainly in the south.
We're talking about 2000 years ago maybe more, that the fine pottery of china was developing.
This 'pillow' was modelled in a typical style of the era and glazed in the familiar green glaze of the northern, more robust pottery.
There are many examples of old celadon pottery in the #shanghai museum but celadon is a European term for the working glaze used.
Wikipedia
Celadon is a term for pottery denoting both wares glazed in the jade green celadon colour, also known as greenware (the term specialists now tend to use) and a type of transparent glaze, often with small cracks, that was first used on greenware, but later used on other porcelains.
The lights in this picture reflected the green poorly - that actual colour is more of a natural Jade colour.
