The "winter green" Celadon ceramics did not actually "end" in production in 
South China, only the trade system got disrupted by civil war and economic 
depressions in America and Europe. Although the general concensus has Celadon 
terminating in the 1920s or early 1930s, it continued in use in China. After a 
particularly interesting SHA session at Philadelphia in 1983, I visited San 
Francisco Chinatown and bought a shoe box full of small Celadon cups and spoons. 
The sales clerk told me the buyer found them in factory kitchens in southern 
China and that he died during one purchasing trip, so the pieces on the table 
were all they expected to receive. She said Celadon continued in use by common 
families long after the export business ended. 

The pieces from San Francisco Chinatown are not as refined as the examples we 
excavate in 19th century American contexts. I found the glaze cruder and the 
porcelaneous ceramic walls a tad thicker. There were still the blue maker's 
marks and etched owner's marks on those small specimens.
