Who Owns Kilner? Unpacking the Brand's History and Current Ownership
For many Americans who enjoy canning, preserving fruits and vegetables, or simply appreciate a classic, well-made jar for storage, the name "Kilner" likely rings a bell. Kilner jars are iconic, instantly recognizable for their distinctive design and their reputation for quality. But as with many long-standing brands, a common question arises: Who owns Kilner? The answer, while straightforward in its current state, involves a journey through industrial history and a significant shift in corporate ownership.
The Kilner Legacy: A History of Innovation
The story of Kilner begins in the United Kingdom with John Kilner. In the mid-19th century, John Kilner was a glass manufacturer. He recognized the growing need for reliable and hygienic containers for preserving food, especially with the rise of home canning. His innovations and the quality of his glass jars quickly set him apart.
Kilner jars are particularly famous for their early designs, which often featured screw-top lids. This was a significant advancement at the time, offering a more secure seal than many other methods. The brand quickly gained popularity for its durability and the effectiveness of its seals, making it a trusted name in households across Britain.
The Evolution of Ownership: From Family to Corporate
Over the decades, the Kilner brand, like many industrial enterprises, experienced changes in ownership. While John Kilner himself was the originator, the business eventually transitioned through various hands. For a considerable period, the Kilner brand was a part of larger manufacturing conglomerates. This is a common trajectory for brands that achieve widespread recognition and market dominance.
The Current Owner: A Global Kitchenware Giant
Today, the Kilner brand is owned by **Rayware Group**. Rayware is a prominent U.K.-based company specializing in the design, manufacture, and distribution of homeware and kitchenware products.
Rayware acquired the Kilner brand and has been instrumental in its continued success and global reach. Under Rayware's stewardship, the Kilner brand has seen a resurgence, with traditional designs being maintained and new product lines being introduced to meet contemporary consumer needs. This includes a range of preserving accessories, different jar sizes and styles, and other kitchen essentials that complement the core Kilner jar offering.
It's important to note that while Rayware Group is the current owner, they operate with a deep respect for the heritage of the Kilner brand. The iconic vacuum seal jars, often referred to as "preserving jars," continue to be a cornerstone of their product line. These are the jars that most Americans likely recognize, featuring the familiar metal screw-top lids with the distinctive Kilner logo.

Frequently Asked Questions about Kilner Jars
How are Kilner jars made?
Kilner jars are primarily manufactured using glass, a material chosen for its durability, non-reactivity with food, and transparency. The manufacturing process involves melting raw materials like sand, soda ash, and limestone at extremely high temperatures. This molten glass is then precisely molded into the iconic jar shapes, often using sophisticated automated machinery. The metal screw bands and lids are manufactured separately and then assembled or offered as part of the jar set.
Why are Kilner jars so popular for preserving?
Kilner jars have earned their popularity for preserving due to their consistent quality and reliable sealing mechanisms. The original screw-top design, with its rubber seal and metal band, creates an airtight vacuum when heated and cooled, which is crucial for preventing spoilage. Over the years, the brand has built a strong reputation for durability and effectiveness, making them a go-to choice for home canners who want to ensure their preserves last. The aesthetic appeal of the classic Kilner jar also contributes to its enduring popularity.
Are Kilner jars still made in the UK?
While the Kilner brand originated in the UK and has a long manufacturing history there, the exact location of production can vary for different product lines and over time. Rayware Group, the current owner, sources and manufactures products globally. However, the brand's heritage and commitment to quality remain central, and they often emphasize their connection to British design and tradition.
What is the difference between Kilner jars and Mason jars?
The primary difference lies in their origin and specific design features. Kilner jars are a British brand, historically known for their screw-top lids with rubber seals. Mason jars, on the other hand, are an American invention, typically featuring a two-piece lid system consisting of a flat metal lid with a sealing compound and a screw-on metal band. Both are excellent for preserving, but they represent distinct traditions in canning history and design.
