Rickard5,
You are very aware of the risks that Lead presents for humans when it ends up in the environment. And similar for Chrome. However, at the moment the politicians that define the laws have set out generic rules roadmap.
Specific for crystal (the glass, not the oscillator part), when that ends up in a landfill, the sun will be a red giant before the lead is freed from the glass. So it will never end up in the ground water. So (specific for lead in crystal) the law is too strict. B.t.w. the law is about Lead content (weight) percentage of the total weight of the part. Actually ppm in weight.
Since a modern oscillator crystal weight is in miligrams, you have to start counting lead molecules in the crystal glass....
