這裡可以參考一下： http://en.wikipedia.org/wiki/Lead_crystal Lead crystal and food safety Significant amounts of lead can migrate from lead crystal containers into beverages stored in them.[1] Lead crystal typically contains 24–35 percent lead oxide. 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.[citation needed] To put this into perspective, EPA's lead standard for drinking water is 15 μg/L = 15ppb.[2] Citrus juices and infant formula leach lead from crystal just as effectively as alcoholic beverages. Several companies do make lead crystal baby bottles and it is suspected they may present a health danger to infants.[citation needed] 看來，鉛的確是會溶出來，不過需要時間，量也很少。通常酒倒出來一下就喝完了，除非你把酒泡在杯子，放上幾天，不然鉛的問題應該微乎其微吧！不過，有些人會把酒存放在醒酒器(Decanter)裡，可能影響會比較大，所以 Decanter 找 lead-free 的可能比較安心。 ※ 引述《lololol (I love Syrha/shiraz)》之銘言： : 因為之前對酒杯沒研究，所以買了一組酒杯 : 後來發現他有可能就是含鉛量很高的水晶杯 : (因為他的色澤很美，很透徹，不易敲破，擊杯時聲音清脆有迴聲...) : 上網查了一下資料發現一般的水晶杯都含24%的鉛 : 甚至有的牌子是高達30%以上(http://0rz.tw/6f3qp) : 文章中還提到 : 如果你擔心含鉛水晶杯危害健康，其實大可放心， : 因為少量的酒並非長時間浸在杯內，鉛分滲入酒的 : 機會很微；至於容量大的水晶酒瓶 Decanter ， Baccarat : 索性作除鉛處理，連近乎零的危險都消除。 : 不知道這是業者安慰人心的話還是真的? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.39.237
