Dear Friends
I am going to write a paper on the Freiberg silver amalgamation
process ( XVIII century) and its evolution and spreading all over the
world ( South America included ). I am looking for information about
the life and the work of B.Krohenke and R. Franke ( both German
consuls , the former in Chile and the latter in Bolivia, at the end of
XIX century). Both of them invented new amalgamation processes, derived
from Freiberg method, used in that areas only. Can someone of you help
me or send me the address of some people experienced in the field?
Sincerely yours Marco Mazza
