Dear Amalia,
I have been quite successful at a nondestructive polishing method of
objects using a dremel drill and drill press. It polishes an area about
two millimeters in diameter. I etch the small area and then look at it
under the microscope. This method works quite well on blades. If you
want more details, just let me know.
Good luck...I love looking at microstructures.
All the best,
Ann Feuerbach

I came across some difficutlies in measuring the carbon content of archaeological iron (roman nails). Using SEM-EDS the percentage measured was particularly high (almost 10%) which doesn't follow the dating of the objects. Furthermore, I was anable to find adequate equipment to perform chemical analysis.
