Finish & Decoration
Niello decorative technique with bright-cut engraving on a matte black background; features a stylized border and central band. Traditional Thai scrollwork.
Hallmarks & Stamps

Construction Details
Rolled sheet silver formed into a cylinder with a visible solder seam; the exterior surface is engraved and filled with niello paste which is then fired and polished flat.
Functional Features
Cylindrical hollow form with smooth interior edges to protect fabric linens; designed for individual place settings.
Handle & Grip Details
None; the item is a simple annular band designed to be held by the outer circumference.
Craftsmanship Details
Hand-engraved and hand-filled; the precision of the engraving against the black niello substrate indicates a skilled artisan, though this was a production piece rather than a unique commission.
Authentication Indicators
The blueish-black hue of the niello and the characteristic engraving style are consistent with authentic Thai sterling manufacture. Solder seams are typical for this period.
Origin & Manufacturing
Bangkok, Thailand (formerly Siam). Produced by specialized workshops using traditional niellowork techniques that date back hundreds of years in Thai history.
Era & Period
Mid-Century Modern / Post-WWII Export Era (1940-1970); characterized by the 'Siam Sterling' boom in the American and European markets.
Age Estimate
Circa 1950-1960. The style of the niello border and the thickness of the silver suggests a mid-20th-century production date.
Cultural Significance
Represents the 'Siam Sterling' movement which helped rebuild the Thai artisan economy post-WWII by catering to Western tastes for exotic decorative arts.
Condition Notes
Fair to Good. Significant surface scratching and scuffing to the niello and silver; visible tarnish and potential minor pits/voids in the niello mixture. Structure remains solid.
Value Estimate
$25.00 - $45.00 USD. Value is driven by silver weight and the popularity of 'Siam Sterling' collectibles; condition issues like niello loss can decrease value.
Care & Maintenance
Clean with a soft cloth and mild soapy water; avoid chemical 'dips' which can damage the lead-based niello. Use a silver polishing cloth for the highlights.
