I used the services of an industrial non-destructive testing facility. They use x-ray to check metal objects for cracks, joints etc. I trust such facilities are available everywhere. Try "non destructive X ray" on Google and you will get thousands of contacts. It is not too expensive. A whole series of exposures (and there were many) cost me less than 200 dollars.
Regarding revealing of a stamp or signature, it depends on the thickness and depth of the stamping. X-ray does not exhibit the best spatial resolution because of what is known as secondary emmited radiation (compton effect). |

Thank you both for some very informative replies and technical notations.
Artzi, I am grateful to you for exposing me to this method and thank you too Anandalal for providing those interesting images of the kastane, I got quite a kick out of seeing those Kastane features in the x-ray. regards Gav |
