Abstract.

The possibility to cause nuclear transmutation of stable isotopes by means of ordinary chemical reactions (1) suggested the possibility to cause nuclear transmutation of unstable isotopes (2).
A first series of experimental tests was made from 1993 to 1995 with positive results (3) .
In 1996 an industrial reactor was built in Canada and sent to Italy for a new series of independent tests at ENEA (Italian National Laboratories).
In these tests the production of Silver from Lead was used as a driver of the nuclear transmutation of Thorium and Uranium (4).
A new series of tests has been performed at the ENEA Laboratories, starting October 1997.

Introduction.

After experiments made at Texas A&M and Engelhard Laboratories in 1992 it was clear, in my opinion, that Alchemy is an experimental science.
As a consequence, following the Principle of Banality (5),throughout my tests, I used one only method: "Solve et coagula" (desolve and coagulate), together with "the right fire and the favourable constellation"(6).
