There is a certain difference between glass and crystal, which, however, changes from country to country or region to region. In most western countries, the word crystal stands for the presence of lead. According to the rules of the European Community, glass goods containing more than 4 per cent of lead monoxide is defined as glass. Glass goods containing more than 10 per cent of lead monoxide is deemed crystal, and finally, glass goods containing over 30 per cent of lead monoxide is classified as lead crystal. In the U.S., 1 per cent of lead is enough for a glass to be classified as crystal. In Bohemia (the Czech Republic), such classification is a matter of interpretation and the term "crystal" can be used for any refined, high-quality glass.
