Hi. Nervous mom again here....was reading about the migration of lead from crystal glasses to juice or wine during a meal. It is estimated that no more than 2 mg per litre of lead is transferred to the glass when drinking out of a crystal vessel during a meal. If this is the case, say a toddler had 2-3 sips out of a crystal glass (thanks to my mother!), how much would she actually have consumed when compared to say, the insanely strict California Prop 65 daily limit for children of 0.5 ug/day?
