I am thinking along the lines of Fired Up in Branford. This place is always packed with a range of “authentic” artists, newbies, kids, and crafters. The point of these places is to provide the pottery and glaze and let your imagination do its thing. Some also provide kiln services for potters who can not feasibly keep their own kilns in their apts/homes. Many also have BYOB bookings and midnight gatherings.
