It could be considerably older than 19th Century - they are hard to date with certainty as they've been made this way for at least three millennia. They are often kept in cool cellars and are sealed for long-term and seasonal storage of all manner of produce: grain, olive oil, figs etc - this shape is used for milk - whether cow, goat or camel. They make wonderful garden ornaments but the milk pots are known to be fired at a lower temperature than other designs so will need protection from frost.
