The Influence of Heavy Metal Ions on the Hygroscopicity of a Glass Surface

JSGT 1948 V32 T260-T263

The affinity of a glass surface to water as affected by the surface ions is discussed. It was found possible to modify a glass surface by treating it with aqueous solutions of metal salts. The theory of this surface beneficiation is discussed briefly and possible applications are suggested. The hygroscopicity test developed by D. Hubbard was found to be a valuable tool for estimating the affinity of a glass surface to water vapour.
