PSA about harmful health effects of ruthenium jewelry 

Huh. Today we learned: Ruthenium jewelry is actually really bad to have

ruthenium metal is perfectly harmless on its own, but it reacts very quickly with bleach to form extremely toxic, bioaccumulating ruthenium salts and, even worse, ruthenium tetroxide gas

this doesn't have to be strong industrial-strength bleach either. common household bleach will do it, like you'd use when cleaning things or doing laundry

re: PSA about harmful health effects of ruthenium jewelry 

@Felthry That is, um, good to know.

How do I know if something's ruthenium? Is it usually mentioned as such, or is it like used to make cheap jewelry that doesn't really say?

re: PSA about harmful health effects of ruthenium jewelry 

@IceWolf They'll say. Ruthenium is nearly as expensive as gold.

re: PSA about harmful health effects of ruthenium jewelry 

@Felthry Ohh, ah okay. I'm fine then. :P

Thanks!

re: PSA about harmful health effects of ruthenium jewelry 

@Felthry [I've got a couple of really cheap rings and don't know what they're made of, so this had me slightly worried. :3]

re: PSA about harmful health effects of ruthenium jewelry 

@IceWolf They'll probably be something cheap like nickel silver or steel.

re: PSA about harmful health effects of ruthenium jewelry 

@IceWolf Or maybe brass or nordic gold, if they're gold colored.

cheap jewelry materials tangent 

@Felthry Nah, they're silver-colored! I think they might actually be silver-plated, but one has started to scratch off on the backside and it's a somewhat duller metal underneath.

re: cheap jewelry materials tangent 

@IceWolf i'm pretty sure you'd know if they were silver plated, they'd tarnish

...though that depends on air quality since tarnishing is mostly due to sulfur-containing gases (like sulfur dioxide and hydrogen sulfide)

-F

re: cheap jewelry materials tangent 

@Felthry Oh huh, neat. :3

Maybe they're plated with something else then. Whatever it is, it hasn't been tarnishing; then again, I think I generally hang out in places with decent air quality. *swishes tail*

re: cheap jewelry materials tangent 

@IceWolf air quality affects the rate, not whether it tarnishes at all. if they've remained silver over months without any cleaning or polishing they are not real silver.
-F

re: cheap jewelry materials tangent 

@Felthry Must not be silver then! It's been months and no change.

I think at the little pop-up stand where I got them, older pieces were this... almost yellowish color.

re: cheap jewelry materials tangent 

@IceWolf that could be silver tarnishing? it turns a wide array of colors before going black
-F

re: cheap jewelry materials tangent 

@Felthry Oh huh!

*pulls out jewelry to take a look*

I also have a wonderful bronze pendant. It's really nice. :3 And I wish they made more stuff out of stainless steel and things. I'd buy solid stainless steel jewelry.

re: cheap jewelry materials tangent 

@IceWolf we have Opinions about the use of non-precious metals and stones in jewelry, mainly of the "this should be more common" variety
-F

re: cheap jewelry materials tangent 

@Felthry Big same! Of course, I also don't do jewelry for the status symbol, I do jewelry because "ooh I can adorn myself with pretty wolf designs". :3

I just got a stainless steel chain for that pendant. It's really nice and really cheap too.

re: cheap jewelry materials tangent 

@IceWolf even for adornment there are *super* pretty stones and metals

like look at aventurine or spessartine or turquoise or amazonite

and look at phosphor bronze or aluminum bronze or beryllium copper

re: cheap jewelry materials tangent 

@Felthry Ooooh. Do they make jewelry out of those? :3

re: cheap jewelry materials tangent 

@IceWolf you could!

beryllium copper maybe not though, since we don't know how they make it and wouldn't want to encourage unsafe beryllium stuff
-F

re: cheap jewelry materials tangent 

@Felthry I mean, the Wikipedia page for beryllium copper has pictures of wrenches made of it, so. :3

re: cheap jewelry materials tangent 

@IceWolf yeah it's used for tools where it's absolutely essential, like when working in places you *absolutely* cannot tolerate a spark (beryllium copper just doesn't spark at all)

but working with beryllium in a foundry sounds like a really good way to get berylliosis and you just know capitalism is going to mean they don't take proper precautions

-F

re: cheap jewelry materials tangent 

@Felthry Wherf, did not think about that!

re: cheap jewelry materials tangent 

@Felthry Also phosphor bronze is /pretty./

re: cheap jewelry materials tangent 

@IceWolf it isssss. and much less dangerous to make! you only have to worry about fire and explosions instead of incurable deadly diseases
-F

re: cheap jewelry materials tangent 

@IceWolf (you don't actually have to worry about explosions i'm sure. using white phosphorus instead of red would be monumentally foolish)
-F

re: cheap jewelry materials tangent 

@Felthry [Okay, maybe it is tarnishing. I do think it might've used to be shinier than it is now.]

re: cheap jewelry materials tangent 

@IceWolf you can fix that right up with a bit of polish or chemical treatment, might want to look into that

the only thing we know about removing tarnishing from is soldering iron tips, not much use in this case

the sal ammoniac would probably destroy the silver, if the high temperatures didn't cause it to diffuse into the base metal first
