copper pipes can be leading your water to the sink. Jus' sayin'
Completely unrelated: After all this time I'm STILL reading the title of this thread as "ProVarinait DATING SALON".
It appears to be brass. I can find numerous references to the positive terminal of the ProVari being brass. None of them from ProVape, but I am pretty sure that is correct. The pin looks more brass than copper, and since it brass is a neutral metal (often used as a dielectric) it would make sense that it would be used in such close proximity to a lot of steel. In a war between active ferrous and non-ferrous metals (like when copper pipe meets steel pipe) the ferrous metal always wins when the invariable reaction of electrolysis occurs.
I therefore stand by my assertion, that the positive terminal for most mods is composed of brass.
EDIT: I will gladly accept correction on this should it prove to be incorrect, so don't be shy!

We already covered that, keep on topic... lol
Copper is not alcohol soluble, verdigris is alcohol soluble. Verdigris isn't copper oxide (ie copper 'rust'). It's either copper chloride/sulfide/sulfate/carbonate (at least a couple of those, I can't specifically remember off the top of my head). Rust (iron oxide) is the chemical reaction between iron & oxygen, therefore iron in open air rusts. Since water also contains oxygen, wet iron also rusts & at a faster pace because of a concentrated contact area. Copper oxide is a darkening of copper, much like aluminum - copper & aluminum 'rust' is brown & black respectively. Those are not toxic. Verdigris is green & blue, copper reacting with other things in the environment, commonly acetic acid. I recall that the process can also be sped up by other compounds in the air, but again, this is off the top of my head & I'm not remembering precisely which. It happens rapidly near the ocean (which is why Lady Liberty went green so quickly & was expected to).
Having a copper sink, plates or cups isn't a problem. Unless you don't take care of them & verdigris begins to form... then you'd have a problem. Even then drinking plain water out of a green cup wouldn't be all that risky (but I sure wouldn't advise it). Drinking a very weak beer (1-2% ABV) will likely make you very, very ill. It could possibly kill you.
Regarding brass, as far as I know, cannot form verdigris due to the make up. Yes, it contains copper, but that copper is altered when it's formed into the brass. There's 2 types of brass, red & yellow. Yellow brass does not contain lead. Red brass contains 3-5% lead (if memory serves). You can easily clean red brass & eliminate the surface lead with a vinegar water solution. Non-surface lead is not an issue.

Male brain tries to read into comment and find hidden meaning and innuendo within said comment...
Thank You Ozwald, I think that I will still try to get a solid copper one, but not attempt to turn it green then, I will just enjoy the sexy color of shiny copper.
Thanks again man... you're very helpful.

You busy tonight?
It is most likely brass. By neutral, I'm assuming you mean inert/passive. Brass is actually less passive than copper, but only slightly. Galvanic corrosion (electrolysis is a procedure to drive a chemical reaction, but I knew what you meant) happens between two different metals when electrons move from one to the other trying to find a balance (also the basics of how batteries work). You can connect copper to brass, but since they're very similar, nothing is going to happen.
The electochemical difference between two metals in an electrolyte causes an electric current to flow and causes one of the metals to ionize. Those ions combine with oxygen or other elements to create corrosion. Cleaning does not help. Which suddenly reminds me why Lady Liberty changed so fast. The salt water in the humidity was the electrolyte aiding the chemical process & speeding it up. But anyhow, the galvanic corrosion potential of two metals depends on several factors such as surface area. If you have an active metal coupled to a passive metal & the passive metal has a larger surface area, the corrosion of the active metal will be increased. If the active metal area is larger, the corrosion rate of the active metal will be decreased. As far as metals go, the most active are things like magnesium, zinc, galvanized steel (go figure) & aluminum. On the passive end we have platinum, gold, graphite, titanium & silver. Stainless steel, bronze, copper, brass & tin are all in the middle of the road. So copper next to brass isn't going to do much. Stainless next to tin, not much either. Gold vs tin is going to be slightly more active, but not all that serious. Gold & Zinc... with the right electrolyte could be a battery. Exposure time is also a factor.
Since your vaping gear has a relatively short exposure time & small contact area it's really nothing to be concerned about.
Hang out with me & you'll learn some chemistry/metallurgy while you get drunk
I love being a brewer.
I kind of like a no-fish tank.
I might just get one.
LOL.

LOL.
Today I managed to stop vaping my ProVari (ON TOPIC! BOOYAH!!) long enough to set up a new aquarium...
It's a 36 Gallon bow front tank, freshwater... No fish yet... Pretty sure I'm gonna do a Cichlid tank...
Anyone else here keep fish? I need to do a lot of learning!
I thought brass alloy usually contains copper and zinc and bronze alloy is usually copper and tin.

Nice work!
I found a good source of info here.

I think they are using a type of brass with an aluminum and tin mix in the alloying process, which produces a nice, stable, electrically conductive brass that actually prevents corrosion since, "Corrosion resistance is improved by the self-healing oxide film aluminium confers." Pretty cool metallurgic information out there on the inter-web.
I think you might be right about that. I don't deal with those very frequently, so I'm not as read up as I should be.
You are spot on, in this case I think I was saved, but only by a technicality. Bronze is principally copper and tin, Brass is principally copper and zinc. I suspect the alloy used for the positive terminals has both tin and aluminum in them, as my previous post notes.
This was an awesome conversation, I love learning about stuff like this, It was the main reason i got into salt water fish tanks oddly enough, Just messing with chemicals and minerals and taking measurements, beer sounds like a blast!!!
Edit: I'm amazed though Ozwald that you didn't enjoy your fishtank, Knowing beer needs the same attention to cleanliness and lots of chemicals to play with, But then again maybe doing that all day you just wanted to come home and relax.

Hey Techno, I asked this before but never saw an answer.
Do you ever use vertical micro coils with any of your RBAs like the ones in the video by RiP Trippers?
You can brew with minimal knowledge of that kind of stuff, but there are a few of us who really geek out on it. It's one of those hobbies that you can take as far as you want. Mix some sugar & water, throw in some yeast, you got beer. Want to study microbiology? Want to learn some chemistry? Want to be a welder? Woodworker? Bore your friends with a discussion on the role lactobacillius & pediococus plays in an aerobic vs anaerobic environment? We got those too.
