is the lead in crystal wine glasses safe
Lead glass The California Department of Public Health lead advisory states, "children should never eat or drink out of leaded crystalware".[16] Leaded crystal wineglasses and decanters are generally not considered to pose a significant health risk, provided that these items are washed thoroughly before use, that beverages are not stored in these containers for more than a few hours, and provided that they are not used by children.[17][verification needed][18]
Stained glass Evidence of stained glass windows in churches and monasteries in Britain can be found as early as the 7th century. The earliest known reference dates from 675 AD when Benedict Biscop imported workmen from France to glaze the windows of the monastery of St Peter which he was building at Monkwearmouth. Hundreds of pieces of coloured glass and lead, dating back to the late 7th century, have been discovered here and at Jarrow.[8]
