What is a Gurgling Jug?

My treasure du jour is a fabulous vintage English "gurgling jug".  I have a soft spot for green majolica glazes with their rich deep colors, which is what attracted me to this pitcher at an outdoor flea market.  Some uses for this pitcher are obvious, water pitcher or flower vase.  Consider using a unique pitcher to set and/or compliment a theme. Imagine this pitcher full with soft coastal style grass centered on a vintage silver tray filled with sea shells and star fish. It is a simple contained centerpiece for a summer beach themed table.  

Gurgling jugs were intended for use as water jugs – they inherited their name due to the sound they made when liquid was poured out.  They were also used as advertising items by breweries, and over the years hundreds were made to advertise ‘Plymouth Gin’.
