Well,, not sure if it makes a difference or not but lead crystal,,in my mind,, would be less risky since it is more or less hardened within the glass mixture !! A pewter plate is fairly soft and has nothing between the food and whatever the pewter mix is made of !! May not be correct but thats just the way I see it !! Then again,, I am 65 years old,,I grew up with lead paint and probably ate my share as a kid,,I also played with left over asbestos insulation since my family was in the building business !! I never heard of anyone back then that had lead poisoning nor anyone getting sick from the asbestos !! Keep in mind that I do not mean those workers that had to breath the microscopic particles for years !! That is where the problem is,, not the occasional exposure !!
