The current approach to assessing chemical durability of waste glasses focuses on a suite of short-term laboratory tests such as dynamic single-pass flow-through (SPFT) tests, static product consistency tests (PCT), and vapor hydration tests. The behavior of the glasses in the three types of tests is quite different, but each test provides insight into the glass corrosion process. The PCT data showed that at constant alumina, silica, and sodium levels the glass durability order for different glass systems is: Boron-series > Boron-Calcium-series > Calcium-series, while the opposite order is observed in SPFT tests. The order for vapor hydration tests is similar to that observed in the PCT tests. The PCT results are consistent with the current understanding of glass structure and are consistent with vapor hydration tests. The SPFT results can be explained using arguments based on solution chemistry.
