Products with less lead oxide, or glass products with other metal oxides used in place of lead oxide, must be labeled "crystalline" or "crystal glass". Only glass products containing at least 24% of lead oxide may be referred to as "lead crystal". In the European Union, labeling of "crystal" products is regulated by Council Directive 69/493/EEC, which defines four categories, depending on the chemical composition and properties of the material. One alternative material is modern crystal glass, in which barium oxide, zinc oxide, or potassium oxide are employed instead of lead oxide. Lead crystal glassware was formerly used to store and serve drinks, but due to the health risks of lead, this has become rare. This naming convention has been maintained to the present day to describe decorative holloware. It is retained from the Venetian word cristallo to describe the rock crystal ( quartz) imitated by Murano glassmakers. The use of the term lead crystal remains popular for historical and commercial reasons, and sometimes simply crystal because "lead" seems toxic to consumers. The term lead crystal is, technically, not an accurate term to describe lead glass, because glass lacks a crystalline structure and is instead an amorphous solid. In marketing terms it is often called crystal glass. Lead glass is often desirable for a variety of uses due to its clarity. Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.
