Crystal glassware refers to high-quality glass that contains lead oxide, which gives it a brilliant clarity and weight. This type of glass is often used to create elegant items such as wine glasses, decanters, and vases. The lead content enhances the glass's ability to refract light, resulting in a sparkling appearance. In addition to its aesthetic appeal, crystal glassware is known for its durability and ability to hold intricate designs. Many artisans use techniques like cutting and engraving to create beautiful patterns on the surface. This craftsmanship makes crystal glassware a popular choice for special occasions and formal dining.
