A chemist gave me enough potassium chromate to have a go. Ground off a
few
mg from some sheet lead , dropped into some chromate solution and a
cloudy
yellowish deposit formed in the otherwise orange liquid - what it is
supposed to do apparently.
Then ground off some known lead free solder , added to some of the
solution
and no yellow.
Then ground off some known SnPb solder and again no yellow - so not so
simple a test as first appeared, Pb and tin are combined too well to
react
?



Well, we all knew that SnPb solder was a stable compound that was not
going
to break down on its own, allowing cartloads of lead to somehow get into
into the environment, as the eco-bollox lead-free solder brigade, would
have
us believe ...

That was what I was thinking. And it wold take more than acid rain to leech
the lead from solder, or lead would not be possible to be used as the plates
in car batteries.
The only "lead" test pens I've seen are in paints section of hardware and at
8 GBP a pop and nothing on the package about being used on more than one
occassion, they can stay on the shelves. Those would be for red lead in
paints, which is not elemental lead, so probably would not work either
