Overview
This is a classic Vitrelle glass mug featuring the beloved 'Country Blue' floral pattern, complete with a distinctive spiral swirl texture molded into the lower half of the body. Manufactured by Corning, this piece represents the pinnacle of late-20th-century American kitchenware engineering, combining delicate aesthetics with legendary durability.
Story
Introduced in the late 20th century, this specific blue rose motif became the backdrop of millions of American family breakfasts. It was designed to match Corelle's incredibly popular 'Country Blue' dinnerware line, bringing a touch of country-chic charm to suburban kitchens.
Maker / Origin
Corning Glass Works, founded in 1851, revolutionized the domestic kitchen by adapting industrial-grade, thermal-shock-resistant glass for home use. Their development of Pyrex and Corelle's laminated Vitrelle glass made them a household name, celebrated for creating dinnerware that was virtually indestructible under normal kitchen conditions.
Condition & Value
The mug appears to be in excellent vintage condition with bright, unfaded decals and no visible chips or flea bites. The presence of the modern thrift store sticker suggests it has been recently handled, but the glass itself retains its original glossy luster. Excellent condition preserves its utility and modest collector value.
