Lead crystal is glass treated with lead oxide to create a higher refractive index and glittering effect. It is fragile and requires careful cleaning and storage. Some types can contain up to 33% lead, which can be harmful if ingested. To reduce risks, store food and drink in lead-free containers and avoid using lead crystal for children and pregnant women.
Lead crystal is made from glass that has been treated with lead oxide and cut by hand or machine to create facets. This gives the glass a higher refractive index and creates an attractive glittering effect that is appreciated around the world.
Englishman George Ravenscroft is credited with discovering lead crystal in 1676. Today, a number of companies are known for its production and produce glassware and serving dishes as well as sculpture, miniatures, jewellery, chandeliers, candle holders, ornaments Christmas, and home furnishing items made of this material.
Lead crystal can be purchased from jewellers, department stores and online specialty stores. Prices vary according to the type of item, manufacturer and quality of the crystal. It is a popular gift for weddings, anniversaries, graduations and bashowers. In fact, lead crystal keepsakes are passed down from generation to generation in many families.
While lead crystal is undoubtedly beautiful, it is notoriously fragile. Because dust can also act as a harmful abrasive agent, great care must be taken to clean and store items made from this material. Experts recommend that owners use a hair dryer on the cool setting to remove dried dust particles from crystal objects. People should avoid using harsh commercial cleaners, but it is safe to gently polish the crystal with a soft, lint-free cloth. To avoid leaving unsightly fingerprints, cleaners always wear gloves when working. If possible, the crystal should be kept in a locked display case.
Some types of crystals can contain up to 33% lead, so people should be careful when eating or drinking them. Acidic foods and beverages, such as pickles, fruit juice, wine, or soft drinks, can leach significant amounts of lead from the containers they’re stored in. Research has shown that exposure to lead can cause forgetfulness, memory loss, nausea, depression, fatigue, joint pain, vomiting and abdominal cramps. High levels of lead exposure can even lead to sterility or brain damage.
To reduce the risks associated with eating and drinking from lead crystal, people should always store food and drink in lead-free containers and only transfer it to the crystal immediately before serving. New crystal can be soaked in vinegar for 24 hours before using, hand washed with a mild detergent, and rinsed thoroughly with warm water. Since the dangers of lead exposure are even more apparent to children and pregnant women, however, it’s best to avoid using lead crystal altogether for these groups.
