Conclusion
The test results have shown that portable XRF with
a 20 second spectrum is not very suitable for measuring
tarnish layer thickness. Perhaps, if the spectrum is rec-
orded for 999 seconds, and not 20, it will become smoother
and it will be possible to measure the layer thickness.
The error is approximately equal to the ratio of the layer
thickness to the depth of analysis in silver and, taking
into account the density, which is approximately 0.04%,
this is very small. To make a final conclusion, modern XRF
and its software calibration are required. To identify
a substance by its spectrum, an identification error is
required that is less than the percentage of possible sub-
stances (now about 30 million are known). Or almost all
substances should be excluded from consideration.
It seems that no one has tried to ground silver arti-
facts. Maybe grounding will reduce the growth rate of the
tarnishing layer, but maybe not. The test is necessary.
