What is the difference between crystal and glass?

Crystal differs from standard glass through added minerals that raise clarity and weight. These minerals allow deeper cuts and sharper edges. Light passes through crystal with stronger refraction, creating sparkle. Glass lacks this density and often feels lighter in hand. Waterford Crystal uses formulas developed to balance strength and visual appeal. The cutting process relies on crystal hardness to hold patterns. Glass tends to show rounded cuts and less shine. This difference explains why crystal carries higher cost and stronger visual presence on tables and displays.
