The origins of leaded glass date back to Roman times, where small windows were created using lead ‘cames’ to set glass into patterns. This craft provided decoration and ensured privacy in public baths and villas. The “diamond leaded light glass” design emerged in medieval times and gained popularity during the
Gothic Revival period in the 19th century. This design featured small diamond-shaped panes held together by lead cames, minimizing waste when cutting glass.
Square leaded light glass also originated in Roman times and became widespread in Europe during the Middle Ages, with variations in pattern complexity emerging in different architectural styles, such as Tudor, Elizabethan, Gothic Revival, and Arts and Crafts. Leaded glass windows remain a popular feature in residential architecture due to their aesthetic appeal and historical significance.
