Wassail Bowl - Swansea Museum - seen here
I've been thinking about this amazing pot kept in Swansea Museum. It's a wassail bowl made in Ewenny Pottery, south Wales in the mid 19th C. The pottery still thrives and is currently run by 8th generation potter Caitlin Jenkins. Her ancestors first began throwing pots in Ewenny in 1610, but there may have been a working pottery there even earlier as clay was first dug on the site in 1427.
The wassail bowl would have been used as part of a folk custom at Christmas time: "...Wassailing bowls were always decorated in the same way and this one has nearly all the expected traditional features...[the] Christmas tradition of carol singing door-to-door grew out of wassailing. The bowl contained mulled wine which the householder drank for good luck before adding more wine to the bowl." seen here
I have also seen a modern replica made in this style and apparently, it is a difficult thing to produce; this piece manages to have an amazing life and spirit in its making in addition to its virtuosity.
On my recent visit to Flow Gallery in London I saw this piece (below) by Kate Malone which has a strong resonance with the form of the wassail bowl although I don't know if it's intentional.
