"Im Jahr 1775 veröffentlichte Pierre Grignon das vorliegende Buch über verschiedene Aspekte der Eisenmineralogie und -metallurgie, das für die Geschichte der Metallurgie und Kristallographie von großer Bedeutung ist.

"In 1775 Pierre Grignon published the present book on various aspects of iron mineralogy and metallurgy which is of considerable importance to the history of metallurgy and crystallography. Grignon was occupied in the commercial operation of a blast furnace and forge plant and his science stemmed from observations on a much larger scale than those of his laboratory contemporaries. He had the opportunity to see large crystals in shrinkage heads of large castings. The first memoir of structural interest 'Mémoire sur les métamorphoses du fer' had been read before the French Academy in 1761, but was not published until 1775. Here, he provides a model of crystal structure which is qualitatively the same as that used by Romé de l'Isle in 1772, by Tobern Bergman in 1773, and particularly by the great Haüy in 1784, and it is not improbable that Grignon's ideas, public but unpublished, provided the stimulus for the mathematical approach of these more famous crystallographers. Although the possibility of solid solutions as a mixed aggregate is implicit in the ideas of many of the corpuscular philosophers, it is Grignon who first describes a crystallographic model of a mixed crystal."
