Hello,

I came across this covered Jar at a local thrift shop and was wondering if anyone could help I.D. it? More info or if you can "read" the mark on the base. It appears to be incised (scratched in with a glaze over the mark.) I am not sure which direction is upright? It is light celadon green with abstract jade green overlay? Not drastic, but you can feel a ridge (if that makes sense.) Made from porcelain. Measures approximately 3" High and 4" wide. Any help or information would be GREATLY appreciated! Thanks so much!
