The method of stabilizing bronze and iron objects which are actively corroding, by the removal of chlorides and other salts using a solution of sodium sesquicarbonate, has been thoroughly investigated. Optimum treatment procedures are suggested. Various factors which may influence the washing process are discussed and experiments have been carried out to determine the mechanism of the process by which bronze is stabilized.
