WAYS TO PREVENT THE PROBLEM

Outside the laboratory, there is no reliable way for consumers to determine whether glassware is lead crystal.

True crystal should be labeled as such and should contain 24%-32% lead oxide. It may be smooth or intricately cut. A single crystal wine glass may cost $15 or $255; a crystal decanter, $50, $1,500 or more.

Scientists for the Food and Drug Administration suggest following these guidelines, originally distributed for consumers worried about lead in ceramic glazes:

1. Don’t store foods in crystal for long periods of time, particularly acidic liquids like wine, fruit juice or vinegar.

2. Don’t use crystal to hold foods--liquid or solid--on a daily basis. Lead is a chronic toxicant that requires daily exposure to pose a hazard.

3. If you are very concerned, simply stop using crystal. There is not enough scientific information to give quantitative evaluations (of the dangers posed).

Warning: Pregnant women and children should avoid consuming anything from crystal.
