Let's pretend I have a girlfriend who bought me a locket that can go on my keychain, however, my keys have been scratching the paint off of this locket.
See picture
Now let's assume for the sake of the argument and because I'm bored, that I'm paranoid and I'm worried about lead poisoning.
How could I.....
1. See if the metal was lead?
Or more likely,
2. See if the metal was made of an alloy containing not lead?
Assume I cannot destroy the locket to test it, for sentimental reasons.

who cares, lol? people have been living in lead houses for decades and nobody's died lol

lead is not cyanide. If you don't have a rash it's fine.

X-ray fluorescence spectrometry

Energy dispersive x-ray spectroscopy would be better. Most SEMs can do it

Side question, is there any kind of law regulating the use of lead in stuff like this that you guys might know of?
>>8307503
How would density help me if it's an alloy?

I know
You don't do tests and determine the composition of common household items?
Do you even /sci/?

Anything I could do at home would be nice but I'll google that.

A lot of electronics are made of lead and many houses you live in (especially the old crappy cheap ones in college towns) are painted with it. Just don't lick it and you should be fine.

If I were you, I would be more worried about the penny.

It looks like tin, if its an alloy containing lead you have nothing to worry about, if its solid lead you still have nothing to worry about. You can eat the whole thing and nothing would happen solid lead can't be absorbed into the body and be deposited in your brain where it really can't do much damage to you anyways because your iq is so low to be worrying about shit like this.

you could pay a lab to analyze it for you, would cost a fortune though. Also if you know anyone in medicine they would have the ability to run a dual energy ct scan, which will provide two unique attenuation coefficients at different energy levels, which is usually enough information to distinguish most types of metals.

a lot of colleges have the equipment necessary to collect this data, an xray source and a spectroscope is extremely accurate for determining everything down to the percentage of each element contained in a metal alloy.
