Glass is generally considered to be a chemically stable material at the normal conditions. However, during the dishwashing process the tableware glass surface is attacked by detergent water solution at elevated temperatures for different time. It results in different type of irreversible glasses surface damage such as milky effect/white layer, iridescence and line corrosion. The goal of this study was to classify and identify different types of the glass surface damages after dishwashing process and find the mechanism of their creation. EDX indicated that the iridescence was characterised by a difference in composition with surrounding glass. The white layer of corrosion products contained high and/or low amount of alkali earth elements, as originated from detergent washing solution.
