It looks at first like a magically suspended teapot, shedding rather science-fiction-style rays of luminescence. In fact, it's an ordinary teapot - umm, acting as a lampshade. (As it's pierced, that means it would be a poor teapot in actual practice... but I digress...)
We are in the tea-room at the Middleport Pottery Attraction in Stoke on Trent. The site is half a loving restoration of a Victorian potbank, half a working pottery factory (using traditional skills).
The willow-pattern painting on these walls is a nice reference to one of the commonest designs you might find on nineteenth century ware.
