This looks like one of the Burnay pots (palayok) from a particular area in the Philippines. I used to have one that a friend sent me while she was visiting family there. I had seen one at the local Philippine market that was for display only.
Some are glazed and used for cooking, many are larger and unglazed, used to store water because the evaporation cools it.
This is a photo of a Burnay pot, no lid.
