Color tests work on almost any amount of nickel and also give false positives

In a specimen that may be a hematite, a strong presence of nickel was found.
Is that possible? While the specimen is very attractive to magnets, tests
positive for nickel, and looks and weighs like iron, it has many pock marks
and some white inclusions that may be quartz. Anyone come across

Thank you for your well explained points.
As I have said many times before, you would make an excellent teacher as your
answers always stimulate more thoughts.
On that note. you acknowledge that nickel free metal does exist but, from
reduced metal and is very small. With all due respect.

Hi
Hello All,
The process described below can result in some false positives. When
working with such a small test specimen, it is imperative you don't
contaminate it during handling or preparation. If you cut and polish
meteorites regularly, you will have an accumulation of dust in your work
This test I believe, will also give a positive test for lead, which is found
in slag residues if you are testing suspected iron meteorites. So be careful
with these!
