The Reactions between Glass and Water

JSGT 1953 V37 T240-T248

The proposed method of assessing the chemical durability of glass is free from many of the disadvantages of previous procedures. The powdered glass of known surface area, contained in a crucible with a sintered base, is subjected to solution at approximately 100° by a stream of freshly distilled water from a fused silica reflux condenser. The progress of the solution is followed by a back titration method on the liquid remaining in the silica flask fitted to the bottom of the reflux condenser.
