Further advances in lead carboxylate coatings: Coating unprimed heritage lead

Abstract

Further to the previously published work in this journal "Towards a new coating for heritage lead", a coating has been trialled with samples replicating aged lead artefacts. Lead was corroded in an oak environment to simulate storage or display in a wooden case then coated with ethanolic solutions of tetradecanoic and octadecanoic acid. X-ray diffraction and electrochemical impedance data suggests an better-quality coating is formed leading to improved corrosion resistance.
