Analysis of the elemental composition of an object is a necessary step in the documentation of the properties of such object for estimating its condition. Metallic artworks are subjected to corrosion and oxidation processes due to reactive agents present in the air, water and in the ground that these objects have been in contact with for hundreds of years. This is the case for archaeological metals that are recovered from excavation sites, as well as artefacts exposed to polluted air. Stabilization of the conservation state of these objects needs precise diagnostics of the accrued surface layers and identification of original, historical materials before further protective treatments, including safe laser cleaning of unwanted layers. This article describes in brief the basic principles and technological aspects of Laser‐Induced Breakdown Spectroscopy (LIBS) (technique) applicability and prospects in the field of corrosion diagnostics.
