The original Kilner Jar was created in the 1840s by John Kilner & Co. a design that has withstood the test of time and is still a popular style for storing homemade jams and preserves because you can reuse them over and over again. Kilner began with only 70 employees in the 1800s, and in 2000 the design, patent and trademark for the original Kilner Jar  was purchased by The Rayware Group which remains committed to developing the much loved brand. While famous for its jars, Kilner’s range has grown to include kits to make your own wines and beers, along with preserve kits so you can make your own jams with everything you need to create a gorgeous homemade gift.
