These jars were purchased at an auction. I can see black specks in all of them, which makes me think they were actually used. The white one with dragons has a seam on two sides, some smears where five toe dragons painted. When light shone through it the all white one seems to have striations in it suggesting it is stone. The Peking Glass one is quite damaged, so not sure worth - but has crane, butterfly and water lily on it.
