About the Author The Kilner business was first established by John Kilner in 1842. Initially producing glass bottles and jars, it was towards the end of the 19th century when the original Kilner Jar was first invented. The original jar is as much-loved and successful now as it was 175 years ago. Its long-lasting popularity is owed to its distinctive pressure seal and iconic design. Put simply, households all over the world trust it to successfully preserve and pickle their fruit and vegetables. In the 1900s, Kilner presented its innovation as 'the original and the best, all other brands are substitutes', a claim which remains relevant today, and is a testament to its impressive heritage.
