A stained glass window is a decorative window made from pieces of colored glass that are joined together by lead or copper framing. These windows are often found in churches, cathedrals, and other significant buildings, where they serve both artistic and functional purposes. The vibrant colors and intricate designs can depict religious scenes, historical events, or abstract patterns. The process of creating stained glass involves cutting glass into specific shapes, painting details, and then assembling the pieces. Artisans use techniques like glass painting and etching to enhance the visual effects. Stained glass windows not only provide beauty but also allow light to filter through, creating a colorful atmosphere inside the building.
