Define American cut glass.

American cut glass refers to a type of glassware that was produced in the United States from the late 19th century to the early 20th century. It is known for its intricate and precise cutting patterns on clear, high-quality glass. American cut glass gained popularity during the Victorian era and became a symbol of wealth and luxury. It was often used for tableware and decorative items. The process of creating American cut glass involved skilled artisans hand-cutting and polishing the glass using various techniques. The glass pieces were typically made from a lead-free formula, which resulted in a brilliant sparkle and clarity. The cutting patterns on the glassware featured geometric designs, floral motifs, and elaborate patterns, often with deep, sharp facets that caught and reflected light beautifully. American cut glass became highly sought after both domestically and internationally. It was frequently exported to Europe and showcased in exhibitions and world fairs, where it received numerous awards and recognition for its exquisite craftsmanship. While American cut glass production declined after World War I due to economic and technological changes, it remains a cherished collectible and a reminder of the rich history of glassmaking in the United States.
