This is a very charming Chinese double gourd vase circa 10th century.
I believe it is found in a river near Palembang in South Sumatera, Indonesia. Or this object is probably found in Musi river.
The condition of this vase is not pretty. I would say the condition is fair, commensurate with the age.
I believe there was green glazing on the vase. Somehow this glazing has gone, probably washed by the river water (?) or it is being overly cleaned when it was found.
This vase probably is from Yue-kiln sites. I am not sure from what Chinese Dynasty is this vase from. Probably Five Dynasties?
The vase is from circa 10th century (AD 901 – 1000). I dated this based on similar collection at the Ashmolean Museum (Yousef Jameel Centre for Islamic and Asian Art). Please see here: http://www.jameelcentre.ashmolean.org/collection/4/7450/7453/11786
Of course the Museum collection is far more superior, full green glazed, and with slightly bigger size than my collection.
