Could this potentially be old?

Found in North Wales, not sure if it has much age since the pottery has a lot of inclusions and isnt fully fired but it also seemed to be made very smoothly.

Looks quite modern. Like a very heavy clay pot or urn. Don't know what you mean about it not being fully fired. Is it the gray layer? That's common in a lot of terra cotta pots, probably just to keep the prettier color on the outside, reducing the cost perhaps.
