Product Details

Pyrex, a brand owned by Corning Inc., is renowned for its durable borosilicate glassware, particularly its bakeware and kitchenware. Introduced in 1915, Pyrex quickly became a staple in American kitchens due to its resistance to thermal shock and chemical inertness. The brand expanded its offerings over the decades to include a wide array of dinnerware patterns, many of which have become highly collectible. This particular pattern, often referred to as 'Old Town Blue' or 'Blue Onion', features a delicate blue floral and vine motif. It was produced by Pyrex and its sister brand, Corelle, during the latter half of the 20th century, typically from the 1970s through the 1980s. These mugs were part of everyday dinnerware sets and are now sought after by collectors for their nostalgic appeal and classic design.
