Instead he performed experiments, which were evaluated in the circle of active and famous scientists, Carl Wilhelm Scheele, Gottlieb Gahn and Torbern Bergman, with whom he shared a great interest in the chemistry of metallurgical processes and their theoretical conditions.

A great authority on iron metallurgy in Sweden (and Europe) was Sven Rinman (Chapter 8, Iron, section 8.7.2). In his Mining and Metallurgical Dictionary (Bergiverks-lexikon) he had described a method to determine whether a specific iron was Hkely to be brittle at about 200°C. This cold brittleness is caused by a high content of phosphorus in the iron. Sefstrom himself described the method in the Transactions ofThe Royal Swedish Academy of Sciences in 1830 ...
