Nickel allergy: It's a problem many women run into when they wear
jewelry. Nickel is a metal that is commonly used in metal alloys. And
not just in cheap materials; even low-content gold is sometimes mixed
with nickel.
An allergic reaction usually occurs when you have been exposed to
nickel for a longer period of time (and if you are sensitive to it, of
course). Most coins, for example, contain some nickel, but we never
touch them long enough to get a reaction. But if you were to wear an
earring with traces of nickel, then that could result in unpleasant
reactions. It may cause itching, eczema, or make your earlobes swell up.
In short, this is something you really don't want when you're wearing
jewelry!
This is why I have always been very cautious about buying metal parts. I
have never blindly trusted my suppliers' promises that their products
were nickel-free.
Recently, I have started testing my metal products for nickel
myself. I bought a nickel-test at an on-line allergy shop. Thy sent me a
plain white bottle, containing a substance called Dymethyl Glymoxime.
You just need one drop on the metal you are testing, and then you rub it
in for about a minute. If your cotton swab turns pink, then your metal
contains nickel.
The first time I tried this out, hardly anything happened. The
cotton swab turned a bit brownish. Was this nickel, or just some dirt or
tarnish on the surface? I looked for some jewelry that I was sure
contained nickel.
This is what happened to the bracelet. I put a drop of the tester
on the back, and the liquid changed colour immediately. This was pink.
This was nickel!
A second bracelet gave even more exciting results. The liquid
spontaneously turned fuchsia and spread through the material. Rubbing
wasn't necessary, the test was positive.
