Specialist Notes
The extraction of boric acid from the lagoons was started in 1818 by the Frenchman Francois Jacques Larderel, who founded the town of Larderello. Since 1827, geothermal steam has been used to heat boric waters; the following year the first rudimentary drilling took place to extract the steam. Thus the Tuscan boraciferous region was born, a major producer of substances such as boric acid, sodium perborate, ammonium carbonate and powdered talc. In 1903 the Florentine Prince Pietro Ginori Conti, son-in-law of the Count de Larderel, became general director of the Larderello Company and started the production of electricity for the first time through the use of geothermal steam (1904). The developments of the geothermal industry born in Larderello have been an example for all the other geothermal areas of the world.
