Type
Hollowware (Serving Bowl/Casserole)
Maker
Buenilum (Frederick Buehner and Otto Lowen), a highly successful American creative partnership established in 1933 following their arrival from Germany. They were pioneers in transforming aluminum into high-design decorative art.
Material
Handwrought Aluminum. Despite its silver-like appearance, this item contains no silver content. It is a high-grade pewter-look aluminum alloy designed to be durable and tarnish-resistant.
Dimensions
Standard serving size; typically 8 to 10 inches in diameter. Aluminum is significantly lighter than silver, likely weighing between 400-700 grams depending on handle size.
Description
A classic example of American Mid-Century aluminum-ware, this Buenilum piece mimics the elegance of hand-hammered sterling silver. The reflective, dimpled surface catches light effectively, while the architectural handles provide a distinct modernist flair. Buenilum was once the 'Tiffany' of the aluminum world, known for pieces that could go from the oven to the dining table.
Key Features
Distinctive castle hallmark, 'Handwrought' stamp, all-over hammered texture, and high-shine aluminum alloy that does not tarnish like silver.
Material & Composition
Handwrought Aluminum. Despite its silver-like appearance, this item contains no silver content. It is a high-grade pewter-look aluminum alloy designed to be durable and tarnish-resistant.
Finish & Decoration
Hammered or 'planished' finish. The surface features visible, rhythmic hammer marks intended to showcase human labor and the Arts & Crafts aesthetic within a machine-age context. It features a bright, lustrous polish.
Hallmarks & Stamps
The base is stamped with the Buenilum trademark: an image of a castle/fortress above the word 'BUENILUM', followed by 'HANDWROUGHT' and a model or batch number (likely 'B').
Construction Details
Handwrought and spun. The body shows planished hammering over a form, with thick, expressive cast aluminum handles attached via integrated soldering or welding.
Functional Features
Includes a wide, stable base and large ergonomic handles designed for serving hot dishes. Aluminum was favored for its excellent heat conductivity and light weight compared to sterling silver.
Handle & Grip Details
Signature Buenilum cast aluminum 'wing' or 'scroll' handles. They are solid, thick, and typically feature more pronounced 'modernist' lines than the bowl itself.
Craftsmanship Details
High-quality 'industrial craft'. While sold as 'handwrought', pieces were often machine-pressed into shapes and then hand-finished with hammers to achieve the desired artisanal texture.
Authentication Indicators
The authentic Buenilum stamp is clear and appropriately struck. The wear patterns are consistent with aluminum rather than silver (aluminum scratches more easily and with different depth and color than sterling).
Origin & Manufacturing
United States; specifically New York (New York City) and later Stamford, Connecticut, where the Buehner-Lanner Inc. factory was located.
Era & Period
Mid-Century Modern (Post-War era), specifically 1940s-1950s. It reflects the American 'Studio' movement transition away from expensive precious metals during and after WWII.
Age Estimate
Circa 1945-1955. The hallmark style and the heavy patina/wear on the base are consistent with mid-century household use.
Cultural Significance
Represents the democratization of luxury design. During the Silver Rationing of WWII and the subsequent economic boom, aluminum became a 'miracle metal' that gave middle-class homes the look of handcrafted silver at a fraction of the cost.
Condition Notes
Fair to Good. There is significant surface scratching on the underside from sliding across tabletops. Dark oxidation spots and pitting are visible on the base and sides. The metal shows typical 'clouding' common in older aluminum.
Value Estimate
$25 - $60 USD. Values for aluminum-ware remain modest unless it is a rare, large-scale designer piece (like a tiered tray or punch bowl). Condition on this piece limits it to the lower end of the range.
Care & Maintenance
Do not put in the dishwasher, as harsh detergents will turn aluminum grey/black. Wash with warm soapy water and a soft sponge. For polishing, use a specific aluminum polish or a paste of cream of tartar and water; avoid silver dips.
Similar Pieces
Wendell August Forge (more folk-art style), Arthur Armour (known for etched designs), and Rodney Kent (frequently utilizes ribbon and tulip motifs).
Interesting Facts
Buenilum is a portmanteau of 'Buehner' and 'Aluminum'. Frederick Buehner's designs were so celebrated they were featured in the Museum of Modern Art's design catalogs in the 1940s.
