Waterford is leaded glass, often just called “crystal” because of its clarity and to not call attention to the lead content which is minimum 25% lead oxide powder by weight https://en.m.wikipedia.org/wiki/Lead_glass https://en.m.wikipedia.org/wiki/Lead_glass > In a study performed at North Carolina State University, the amount of lead migration was measured for port wine stored in lead crystal decanters. After two days, lead levels were 89 µg/L (micrograms per liter). After four months, lead levels were between 2,000 and 5,000 µg/L. White wine doubled its lead content within an hour of storage and tripled it within four hours. Some brandy stored in lead crystal for over five years had lead levels around 20,000 µg/L For ref the EPA limit is 15 µg/L and even that is prob on the high side since the human body has 0 use for any level of lead
