La présence de scories de fonte dans des creusets n'apporte pas la preuve d'une fonte du cuivre dans des creusets. Copper-rich lumps of smelting slag had been sent from the smelting sites to the Temple and was melted in small crucibles to provide copper for the casting of votive figurines.

The particular location of the Puy Beaunit, above a fertile mantle and close to a major fault active during Permian times, explains why the mafic/ultramafic xenoliths from Beaunit are exceptional compared to the suite of late-Variscan granulitic xenoliths in the FMC.

Alkali metals react vigorously with water, producing hydroxides and releasing hydrogen. The reaction with air covers the surface of the solution with oxides. In nature, ionic compounds (salts) contain alkali metals but never in a pure state.

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive non-crystalline silica found in many common aggregates, given sufficient moisture.
