Leaching of Glass

Leaching of Glass
Corrosion of potash-lime-silica glass studied by InfraRed Reflection Absorption Spectroscopy (IRRAS): The dependency of glass composition on the resistance to the leaching processes was tested using different acidic solutions (sulphuric, nitric and hydrocloric acids). In particular the corrosion rate has been shown to be dependent on the type of acid for the same pH conditions. A reflection unit for IRRAS, which was designed and built in the institute, could be used to monitor the changes occurring on the glass surface during the weathering carried out in-situ using synthetic air with controlled relative humidity and contents of acidifying gasses.

Weathering of Glass

Weathering of Glass

In the framework of the Working Group on Effects on Materials Including Historic and Cultural Monuments of the Economic Commission for Europe within the United Nations (UN/ECE) the effects of various air pollutants as well as climatic parameters on the atmospheric corrosion (weathering) of glasses was investigated.
