  contain cadmium, 

With all due respect plat. solders cannot contain cadmium
because of the interaction with plat.(it makes the plat. brittle)

One other point cobalt is hypoallergenic also, and has been used
in medicine for many years

On very rare occaisions, I have found customers that were having
reactions with 18K. On these rare occaisions, I have always found
platinum to be a satisfactory replacement. Pete! You got a email
address?

Kat, Adding to Juergen’s post. It is possible for some rare
folks to be “sensitive” to anything. Speaking from personal
experience, I’d suggest trying a one, two,or three day test with
a small piece of platinum on your customer’s skin. If she/he can
tolerate hypo-allergenic tape ask the customer to tape it on. If
not it can be tucked in clothing or held in place with a binding
of 100% cotton. If it becomes bothersome in any way during the
testing period ask the customer to remove it and note the kind
of reaction that caused the discomfort. That should give both
you and your customer some needed info and a lot of peace of
mind. Joyce

I’ll take your word on that point. Would have figured that as
well until recently, when I noticed that one catalog I get
platinum solder from specifically says, next to the platinum
solders, that these solders may contain cadmium. They don’t give
actual analysis of the solders, so I just assumed it to be
possible. Of course the possiblity may also be a typo, or
simply a warning the printer is used to placing near all
solders…

Thanks. Didn’t know about that, one way or the other.
