Construction Details
Machine-stamped or spun from a flat sheet of aluminum. Includes a registered trademark symbol indicating mass production.
Functional Features
Heat-conductive flat base for stovetop cooking; likely featured a riveted handle (now missing or out of frame).
Handle & Grip Details
Handle not visible in image, but typically would be a black phenolic (Bakelite) or riveted metal handle.
Craftsmanship Details
Industrial machine-stamped quality. Significant for its uniformity and durability rather than artisanal silversmithing techniques.
Authentication Indicators
The 'Mirro' brand name and 'Manitowoc' location are definitive proof of its identity as aluminum cookware. The lack of silver hallmarks confirms it is not a precious metal.
Origin & Manufacturing
United States; Manitowoc, Wisconsin. Manufactured in a high-volume industrial factory environment.
Era & Period
Late 20th Century (post-1963 based on the appearance of the ZIP+4 code in the stamp).
Age Estimate
Circa 1980-2000. The inclusion of the nine-digit ZIP code (54221-1330) confirms a post-1983 manufacture date.
Cultural Significance
Represents the shift toward mass-produced, affordable aluminum kitchenware in American mid-century and late-century households, moving away from heavier cast iron or expensive copper/silver-clad vessels.
Condition Notes
Poor to Fair. The surface shows heavy oxidation, carbon buildup (burnt residue), and deep scouring scratches from abrasive cleaning.
Value Estimate
$5.00 - $15.00 USD. Value is based strictly on utility as cookware; it has no bullion or 'silver' melt value.
Care & Maintenance
Clean with warm soapy water. For heavy carbon buildup, use a commercial aluminum cleaner or cream of tartar paste. Avoid the dishwasher to prevent darkening/pitting.
Similar Pieces
