Lead crystal has been used for centuries and some of the finest glassware in the world is still made from this material. Recently, there has been some concern about its use in serving food and drink.
Over weeks and months the lead used in glass containers can leach into stored beverages. To prevent this, avoid storing liquids for long periods of time in lead crystal containers. Research has proven that everyday drinking and serving from these vessels does not pose a risk. To be safe, the Food and Drug Administration recommends you do not feed babies from lead crystal bottles and you avoid lead crystal glasses if you are pregnant.
California’s Proposition 65 requires a warning of potential dangers, including birth defects, from consuming food or beverages served or kept in full lead crystal.
