Hey, just posting so people wouldn't get too freaked out over their grandma's leaded crystal <img src="/images/graemlins/smile.gif" alt="" /> The risk is extremely low to negligable you will get it from an occasional drink out of leaded crystal... the EPA puts much higher priority on risks of getting lead poisoning from housepaint and leaded paint on ceramics, especially if either was from before the 80's. Lead crystal is not something to totally discount, but the risk is more for liquids stored in containers, such as decanters, for long periods of time. So go ahead and break it out for the holidays, use for special occasions is fine!
Here's a site with some more info:
