Historical Background
Edward Joy & Sons Limited was founded in Leeds in 1807, establishing itself as one of Britain’s oldest oil and lubricant producers. Originally serving the textile and engineering industries of northern England, the company expanded its operations throughout the 19th and early 20th centuries to supply lubricants for machinery, vehicles, and industrial use.

By the 1930s and 1940s, Filtrate had become a household name among motorists and engineers. The company specialised in producing high-quality oils and greases designed to meet the demands of modern machinery. Their use of colloidal graphite, produced under license from Acheson Industries, was a key selling point. Graphite provided superior lubrication under extreme pressure and temperature, making it ideal for engines, gears, and precision components.

The Acheson process, invented by Edward Goodrich Acheson in the late 19th century, produced finely divided graphite particles suspended in oil, forming what was known as “DAG” (Deflocculated Acheson Graphite). This gave Filtrate products enhanced anti-friction and anti-wear properties, appealing to both professional engineers and home mechanics.

Filtrate’s packaging design evolved during the mid-20th century to reflect the shift toward modern, high-performance branding. The use of bold colours, clean lettering, and technical claims reflected confidence in British engineering and industry. Products like this penetrating oil were marketed as essential tools for maintaining everything from bicycles and farm machinery to aircraft components.

Design and Features
The can’s design captures the aesthetic of post-war British engineering: practical, robust, and informative. The blue background symbolises reliability and technology, while the yellow accents draw attention to key information. The slogan “Between Trafalgar and Waterloo” cleverly connects the company’s founding year of 1807 with two defining moments in British history, suggesting a legacy of endurance and national pride.

The inclusion of the “DAG Colloidal Graphite” mark demonstrates a collaboration between Edward Joy & Sons and the Acheson Colloids Company, an international partnership that underscored the global reputation of British lubricants at the time.

The metal construction of the can made it both reusable and durable. It was designed to withstand workshop conditions while preventing contamination of the oil inside. The screw cap provided a secure seal, an important feature in maintaining the quality of penetrating oils.

Collectibility
Filtrate cans, particularly those featuring the blue and yellow design with the DAG logo, are now highly collectible among enthusiasts of vintage garage memorabilia. They represent a transitional era in British industry when craftsmanship, chemistry, and design combined to produce durable, practical goods that were also visually distinctive.

New old stock or well-preserved examples are rare, as most were used and discarded over time. Collectors appreciate these items for their historical connection to British engineering heritage, their graphic design quality, and their link to the evolution of industrial branding.
