SEM-EDX ANALYSIS QUESTIONS

Referring to Ron Kay's note on February 11, Ron Abler writes: "I
looked up SEM-EDX on the web and quickly submerged myself below the
drowning level in too much unfamiliar terminology to answer two
simple questions:  Is it non-destructive, and how much does it cost?
If it can be used non-destructively, and if I could afford it, there
are a lot of Centennial medals which pose questions that SEM-EDX
might be able to answer. For example, is a darkly toned medal actually
bronze, copper, brass, bronzed, or something in between?  Same with
white metal vs. pewter.

"Maybe Mr. Kay can shed some light into the dimly illumined
recesses of my inquiring mind?"
