Use of Bacteria To Stabilize Archaeological Iron

Julien Maillard

Iron artifacts are common among the findings of archaeological excavations. The corrosion layer formed on these objects requires stabilization after their recovery, without which the destruction of the item due to physicochemical damage is likely. Current ...
