Large water pot

Hi all, I would very interested to know if anyone could throw a date at this, its a large deep green glazed water pot/carrier? with unglazed base and glaze dripping to base very thick body and lid (I assume to keep the water hot) it seems a similar colour as a lot of the Ming ginger pots around at the moment, its quite large being around 9 inches high and 7 inches wide, I like it a lot, but what do you think?
