Kilner was established in England in 1842 by John Kilner. The brand is known for glass jars used for food preservation and storage. Airtight jars allow people to preserve fruits, vegetables, and homemade foods through methods such as pickling or fermenting. Reusable glass containers provide an alternative to disposable packaging and support long-term food storage. Kilner products remain widely used for preserving and organizing ingredients in the kitchen.
