Kilner was founded in the early 1800s with the creation of the first Kilner Jar by John Kilner & Co. The familiar design has been a popular choice and continues to be a recognisable and reliable style of jar, particularly for homemade jams and preserves. After beginning so long ago with only 70 employees, the brand grew and was eventually purchased by The Rayware Group in 2000, after years of difficulty due to other companies stealing the design. The Rayware Group remains committed to developing the brand, and the Kilner range has expanded to include make your own wine and beer kits along with supplies to make your own jams to be beautifully packaged and given as a thoughtful gift.
