Vintage etched floral champagne coupe glass with a faceted stem. Champagne coupes, also known as champagne saucers, became popular in the early 20th century, particularly in the Art Deco era. Their wide, shallow bowls were designed to allow champagne to oxidize and release its aromas, though they are less effective at preserving carbonation compared to flutes. These glasses were often adorned with decorative etching or cut glass patterns, reflecting the prevailing aesthetic trends of their time. Etched glassware, especially with floral motifs, was a common decorative technique used by many glass manufacturers throughout the 20th century. While specific patterns can sometimes be attributed to particular makers or periods, many vintage etched glasses are unsigned, making precise identification challenging. These pieces are often collected for their aesthetic appeal and as functional tableware for entertaining.
