This set of nesting bowls features the Autumn Harvest pattern, a beloved design released by Pyrex (Corning Glass Works) in 1979 and produced through the mid-1980s. Often affectionately called "Autumn Wheat" by collectors, the pattern was designed to complement the earthy, rustic kitchen trends of the late 70s, featuring white wheat stalks printed on contrasting shades of "Rust" and "Orange" opal glass. As part of the "New Pyrex" era, these bowls were made of tempered soda-lime glass rather than the original borosilicate, designed to be durable enough for the modern convenience of microwave ovens while maintaining the classic nesting silhouette that had made Pyrex a kitchen staple since the 1940s. Today, this set is a nostalgic favorite for vintage enthusiasts, representing the final decade of Pyrex’s iconic opal glassware production in the United States before the line was transitioned to clear glass. No chips or damage. Dimensions: 14.5cm (diameter) x 8.5cm (h) / 18.5cm (d) x 9.5cm (h) / 22cm (d) x 10.5cm (h)
