Rare 19th Century Amethyst Glass Cream Jug 1830-1860

Exceptionally rare 19th century amethyst glass cream jug dating to c.1830-1860. Poring section to the front with an applied handle. Very unusually it has an applied blade collar just below the handle terminus. Polished pontil. Weighs 390 grams, shows excellent hand made tooling and fine genuine wear to the base. We were unable to find another example and have never had one. The manufacturing characteristics would place the jug early in the early to mid 19th century. Date & Origin:- England, 1830-1860
