Art Deco glass refers to decorative glassware produced during the Art Deco movement, which flourished from the 1920s to the 1940s. Characterized by bold geometric shapes, vibrant colors, and luxurious materials, this style often features intricate patterns and motifs inspired by modern technology, nature, and ancient cultures. Common types of Art Deco glass include vases, bowls, and lighting fixtures, often made from materials like crystal, pressed glass, or molded glass. Notable designers, such as René Lalique and Daum, contributed to the popularity of this style, creating pieces that are now highly sought after by collectors and enthusiasts.
