german silver/nickel silver allergy?

--- Quote from: Benta on September 09, 2022, 07:33:21 pm ---I very much doubt that German/nickel silver (German: "Neusilber") will provoke an allergic reaction. It's also known as "hotel silver", as most hotels use such tea/coffee pots in their restaurants as well as other "silver" cutlery. (knives, forks, spoons).

The English Wikipedia article about German silver even mentions nickel allergy in it…
Regardless, nickel allergies generally require prolonged exposure (which, as the German wiki article about nickel points out, is difficult to define), not just brief contact, which is why nickel is theoretically banned in the EU for jewelry, etc.

I only have a few square inches of the stuff anyway. Mainly just curious, it feels like its already subsiding. feels like I am gonna ruin a good day to itchyness if it does turn out to be the culptrit.. because I bearly had any contact with it and the rash covers my entire pointer finger top surface to the first joint (1x0.5 inches)

If you barely had any contact with it, then it’s likely not the cause. Nickel allergies generally manifest as reactions where the nickel has been in direct contact with skin for prolonged periods of time, like with jewelry or watches, and where sweat mobilizes the nickel. Brief contact just isn’t enough.
The only way I could envision a nickel reaction here is if you did something that released it as a powder that stuck to the skin (the way metal dust gets really stuck to the skin, to the point it’s difficult to wash off, when sanding metals). Then it might have had enough time to react. But you didn’t mention any process that would have created metal dust.
Ian.M:
The O.P. "noticed what looks to be a tiny patch of rust on the german silver sheet, it was in a basement shelf for a long long time", so there was obviously some surface oxidization, and was straightening out bends in the sheet, which would have disturbed the oxide layer, so its quite likely he came into contact with trace quantities of finely powdered nickel salts.
coppercone2:
you know I think I tracked down the real culprit
It looks like the new hot sauce I got has ghost peppers in it (bought this sauce a few days ago with a assortment of new never tried before spices/sauces/etc to try to cut down on eating out with new flavors). I made a bacon egg and cheese sandwich last night that had some of the ghost pepper sauce on it. Now I have the rash on both pointer fingers and thumbs, aka where the sauce smeared when I was eating the sandwich (i put ketchup and alot of the ghost pepper sauce on it)... and I think I got a small blister on the back of my tongue.
It looks like this type of pepper is significantly hotter then what I normally buy, even if the sauce is edible. I think this is because I wiped and not washed my hands after eating it. Maybe its an allergy to the sauce, but it says the ghost pepper is 1million scoville units, while the habanero is 0.3million (normally I don't go past tobasco*).. I did not realize what I bought in the store. It was not really causing a problem during eating, but the day after.
Again I find this confusing because IMO a sauce like tobasco habanero (not the normal tobasco, the habanero infused kind.. which I actually did not buy in a long while because its too hard to use other then literarly addding drops to sauce pot cooking, its not usable on sandwiches for me imo) tastes WAY spicier then this ghost pepper sauce, which is spicy, but it was nothing that made me consider it being potentially dangerous for my skin.... and I never had a problem with that, other then it being really spicy at the time of eating.

so I think its safe to maybe assume for now that its the god damn ghost peppers, unless of course, metal allergy caused an increase sensitivity to ghost peppers.
Wallace Gasiewicz:
You are probably correct in that it was the ghost peppers.
Nickel allergy usually requires a long time to cause a skin reaction, usually hours, not minutes.
Whatever you do, when handling anything like ghost peppers or lesser peppers, WASH your hands BEFORE going to the bathroom
No doing this causes interesting dance moves with unsynchronous verbal responses.
