Type
Hollowware, Tea Service (Sugar Bowl)
Maker
International Silver Company, based in Meriden, Connecticut. Formed in 1898 as a conglomerate of major American silver manufacturers, including Simpson, Hall, Miller & Co. who originally debuted this pattern.
Material
Sterling Silver (solid .925 purity). Authentic examples in this heavyweight floral relief were primarily produced in sterling rather than plate.
Dimensions
Estimated 3.5 to 4 inches in height. Weight approximately 180-250 grams depending on whether it is handles-integrated or has a weighted base.
Description
A magnificent example of American Art Nouveau hollowware, this Frontenac sugar bowl showcases the opulent 'Lily' motif that made International Silver famous. The design features dramatic, deep-sculpted flowers and curling leaves that wrap around the vessel's circumference. The generous proportions and heavy gauge of the silver reflect the luxury of the Edwardian era dining table.
Key Features
Highly raised repoussé floral shield, scroll-cast handles, and the characteristic 'lily-pad' style textures in the pattern recesses.
Material & Composition
Sterling Silver (solid .925 purity). Authentic examples in this heavyweight floral relief were primarily produced in sterling rather than plate.
Finish & Decoration
High-relief repoussé and chasing featuring a lush Art Nouveau lily and foliate motif. The surface shows a bright polish with oxidation in the deep recesses of the floral pattern to enhance the three-dimensional effect.
Hallmarks & Stamps
Usually stamped 'STERLING' with the International Silver Co. 'knight/shield' logo or the Simpson, Hall, Miller & Co. 'Eagle and WM Rogers' variant. Specific assay marks are absent as was standard for early 20th-century American production.
Construction Details
The body is likely die-struck or pressed to achieve the deep repoussé pattern, then hand-finished and chased. The handles and pedestal foot are cast and silver-soldered to the main cup.
Functional Features
Open top design without a lid (intended for sugar cubes or granulated sugar in a tea set), twin handles for easy passing, and a flared pedestal base for stability.
Handle & Grip Details
Cast solid sterling silver handles featuring foliate scrollwork that echoes the main Art Nouveau theme, attached via high-temperature silver solder.
Craftsmanship Details
Excellent factory craftsmanship; the die-work used to create the central floral shield is remarkably crisp, indicating well-maintained master hubs and high-quality striking.
Authentication Indicators
The depth of the floral relief is a hallmark of the Frontenac series; cheaper 20th-century imitations lack this sculptural quality. The solder seams at the handles are consistent with early 1900s factory production.
Origin & Manufacturing
United States; Meriden, Connecticut. Manufactured using industrial die-striking techniques combined with hand-tooling in a factory setting.
Era & Period
Art Nouveau (circa 1890-1910). The pattern's heavy floral naturalism and sinuous lines are quintessential examples of the American interpretation of the French style.
Age Estimate
Circa 1902-1920. The pattern was most popular in the first two decades of the 20th century.
Cultural Significance
Represents the 'Gilded Age' transition into Art Nouveau, where American households sought to emulate European aristocracy through increasingly ornate and specialized serving pieces.
Condition Notes
Very Good. Visible surface scratches (swirl marks) consistent with improper polishing or storage in a bin. Note the yellowing tarnish which indicates sulfur exposure. No visible dents or structural cracks.
Value Estimate
$250 - $450 USD. Value is driven by the silver weight and the enduring popularity of the Art Nouveau pattern among collectors.
Care & Maintenance
Clean with a non-abrasive cream like Wright's Silver Cream. Use a soft horsehair brush to remove tarnish from the deep crevices. Store in Pacific Silvercloth to prevent the heavy yellowing seen in the photo.
