Elegant table settings have sparkled with lead crystal for over 300 years, ever since its discovery in 1675 by English glassmaker George Ravenscroft. While the term "crystal" has come to signify all fine glassware, true lead-crystal pieces are made with the addition of lead oxide, which gives the glass its exceptional brilliance and clarity. Another hallmark characteristic of lead crystal is that it creates a high-pitched sound when you tap it with a spoon or your finger.
Full-lead crystal, containing 24 percent or more lead, may appear delicate but in fact is extremely resilient. Its strength allows manufacturers to craft feather-light stemware with crystal-clear bowls that show off the wine's color and thin rims, so sipping wine is more enjoyable. Although not visible to the eye, the surface of lead crystal is coarser than regular glass. Thanks to this microscopic roughness, a lead-crystal glass allows wine to develop more intense aromas, further adding to its pleasure.
