Abstract
This paper studies the corrosion of patinated and unpatinated bronze by acetic and formic acid vapours, sulphur dioxide and sodium chloride salt particles, at 100% relative humidity. Weight loss, X‐ray diffraction, infrared and scanning electron microscopy were the techniques used. Acetic and formic acid vapours, sulphur dioxide and sodium chloride produce a high corrosion rate on bronze. In general, no protective effect was found by the patina on bronze. The principal compounds identified were Cu~2~O, Cu~2~S, Cu~5~(SO~4~)~2~(OH)~6~ · 5H~2~O, Cu(CH~3~CO~2~)~2~ · XH~2~O and Cu(HCO~2~)2.
