Is it true that lipsticks which contain LEAD will turn black when rubbed with gold?

I received an email warning about the dangers of Lead as an ingredient in some brands of lipsticks.


To test if Lead was contained it's suggested to put some lipstick on your hand and use a gold ring to scratch on the lipstick, if the lipstick colour changes to black, then you know the lipstick contains lead.





I wanna know if that test would really work ^_^Is it true that lipsticks which contain LEAD will turn black when rubbed with gold?
Um, no.
