Crystal is a high-quality glass containing lead oxide or other mineral additives that enhance its clarity, brilliance and weight. Renowned for its exceptional light-reflecting qualities, crystal has been used for centuries to produce chandeliers, drinking glasses, decanters, bowls and decorative objects. Antique crystal is particularly admired for its hand-cut decoration, sparkling appearance and fine craftsmanship, with English lead crystal becoming internationally celebrated during the Georgian and Victorian periods. *Related Terms*\ Brilliant Cut Glass, Chandelier, Cut Glass, Decanter, Lead Crystal, Lustre, Pressed Glass.
