Abstract
The application of ion chromatography, conductometry and total carbon analysis to the study of desalination of 18th century tiles and mortar s is described. Ion chromatography is shown to be a simple and adequat e technique for the identification and quantitative analysis of ions w hich are extracted during desalination. Chloride, nitrate, sulphate, c arbonate, sodium, potassium, calcium and magnesium were always found i n the immersion waters, and occasionally also nitrite and oxalate.
