The organ cabinet represents a specific corrosion environment with a high concentration of organic compounds that are released into the environment during the degradation of wood, glues and varnishes used in the production of the organ cabinet. Moreover, most of the metals from which organ pipes are made are highly sensitive to organic substances. In this study, the effect of relative humidity (54% and 75%) and concentration of organic compounds (formaldehyde, formic acid, acetic acid and propionic acid) on the corrosion of metals (lead, lead-tin alloy, tin and zinc) from which organ pipes are usually made was monitored. Corrosion rates were determined using gravimetric data (mass gain) and the composition of corrosion products was analysed by XRD.
