Most similar pitchers are aquamarine or brown and made from bottle or window glass. This rare blue example probably came from a bottle factory. The style of applied decoration, which is called “lily pad” by collectors, was employed only in glasshouses in New Jersey, New York, and New England, although it had some predecessors in continental Europe. Because these objects were made after-hours by the glassblowers, never as production pieces, each of them is unique and therefore highly collectible. It is seldom possible to attribute them to particular glassblowers or even to specific glasshouses.
