Effect of organic acid vapors on the alteration of soda silicate glass

Organic acids were previously shown to be involved in the alteration of historic soda silicate glasses in humid atmospheres under museum storage conditions. The present study investigates the role of these pollutants on the visual, compositional and structural modification of soda silicate glasses. Replica glasses aged in humid or humid/acidic...

Alteration of soda silicate glasses by organic pollutants in museums: Mechanisms and kinetics

The role of the organic pollutants formic acid, acetic acid and formaldehyde in the alteration of unstable soda silicate glasses is examined through SIMS depth profiling of replica glass aged in polluted and non-polluted atmospheres under ambient conditions. The effect of different controlled atmospheres is compared to the polluted atmosphere...
