History
John Kilner (1792–1857), namesake and inventor of the Kilner Jar
The Kilner Jar was invented by John Kilner (1792–1857) and associates and manufactured by the Kilner glass bottlemakers company from Yorkshire, which he set up. The original Kilner bottlemakers operated from 1842, when the company was first founded, until 1937, when the company went into liquidation.
In 2003, The Rayware Group purchased the Ravenhead name, including Kilner jar (a subsidiary of Ravenhead), and continues to produce them today in China.
