Mid-Century Style Matte Finish Sand-Cast Aluminum Square Bowl (Frequently Misidentified as Silver)
Hollowware/Decorative Bowl · Unknown; likely an American or Mexican giftware manufacturer such as Arthur Court, Mariposa, or Wilton Armetale, which specialize in silver-alternative alloys.
Pattern: Generic Mid-Century Modern Minimalist Square Form; non-specific pattern.

Type
Hollowware/Decorative Bowl
Maker
Unknown; likely an American or Mexican giftware manufacturer such as Arthur Court, Mariposa, or Wilton Armetale, which specialize in silver-alternative alloys.
Material
Sand-cast Aluminum Alloy (often called 'Armetale' or 'Pewtarex'). This item is not silver; it contains no silver content and is a base metal alloy designed to mimic the look of pewter or matte silver.
Dimensions
Estimated 6x6 inches square, height 2 inches. Aluminum is significantly lighter than silver; this piece likely weighs 300-500 grams, whereas a sterling bowl of this size would exceed 700 grams.
Description
This square decorative bowl features a muted, leaden-grey finish achieved through sand-casting aluminum. Unlike the high-shine of sterling silver, this piece offers a rugged, industrial aesthetic. The soft-rounded corners and heavy walls provide a substantial feel, making it suitable for both functional food serving and as a catch-all decorative tray.
Key Features
Sand-cast grainy texture on the underside, thick-walled construction, and 'silver-alternative' matte grey patina.
Material & Composition
Sand-cast Aluminum Alloy (often called 'Armetale' or 'Pewtarex'). This item is not silver; it contains no silver content and is a base metal alloy designed to mimic the look of pewter or matte silver.
Finish & Decoration
Matte, non-reflective sand-blasted finish. The piece features a 'pitted' texture characteristic of sand casting, with no engraving or ornate decoration, following a Brutalist or Minimalist aesthetic.
Hallmarks & Stamps
None visible. This type of cast aluminum often carries a textured logo on the underside or simply 'Made in USA/Mexico,' though tarnish and surface wear on this piece appear to have obscured any shallow marks.
Construction Details
Sand-cast. The molten metal was poured into a sand mold, creating the grainy texture visible on the base. It is a solid, single-piece construction with no solder joints.
Functional Features
Four black felt or foam adhesive pads have been applied to the base to prevent the rough cast metal from scratching furniture surfaces.
Handle & Grip Details
No handles; the rim of the bowl acts as the primary grip point.
Craftsmanship Details
Industrial quality. The piece is machine-finished after a rough casting process. It lacks the refinement, thin edges, and hallmarks of professional silversmithing.
Authentication Indicators
Lack of 'Sterling' or '925' marks; presence of adhesive furniture pads (rarely found on high-end silver); cast grain structure inconsistent with wrought silver; overall color is too grey/blue for precious metal.
Origin & Manufacturing
Likely USA or Mexico. This manufacturing style was highly popular in the Pennsylvania 'Pewter-look' industry (Wilton) and Mexican artisan Exports.
Era & Period
Late Mid-Century Modern (c. 1970-1990). The simple geometric form reflects the move toward industrial materials in home decor during the late 20th century.
Age Estimate
Circa 1975–1995. The degradation of the adhesive on the protective pads and the specific dull oxidation pattern suggest a piece several decades old.
Cultural Significance
Represents the 'Easy Care' trend in American dining, where homeowners sought the prestige of silver-colored hollowware without the intensive maintenance of real silver.
Condition Notes
Fair to Good. Visible surface oxidation 'pitting' (white spots) suggests exposure to moisture or salt. The protective pads are misaligned, indicating heavy use. This metal does not tarnish like silver (black) but oxidizes into a dull grey/white powder.
Value Estimate
$5.00 - $15.00 USD. These items are common at thrift stores and estate sales and hold no scrap value in the precious metals market.
Care & Maintenance
Do not use silver polish. Clean with warm soapy water. Aluminum is sensitive to acidic foods (citrus/vinegar) which can cause permanent pitting. To restore luster, use a very fine 0000 steel wool or a specialized aluminum cleaner.

Interesting Facts
Sand-cast aluminum became a popular 'silver alternative' in the mid-20th century because it is oven-safe, freezer-safe, and does not require constant polishing like sterling silver.
