Soda lime silica (SLS) glass is the most widely used glass materials in terms of mass in windows, bottles & containers, etc. One of the biggest challenge for SLS glass is its brittleness or propensity to be damaged at ambient conditions. One important reason is that cracks propagation on the SLS glass surface can be significantly accelerated by tensile stress induced corrosion reactions of amorphous silicate network, which breaks the Si-O-Si bonds to form two silanol groups, known as stress corrosion effect. It has also been found that stress corrosion reactions are faster with the increase of relative humidity (RH). The propagation of cracks will eventually lead to the failure of SLS glass. However, very little is known on the reactions between glass and water in the environment induced by interfacial shear, which results in the removal of SLS glass.
