Based on the results presented, it seems both dissolution types (congruent and diffusive) have been demonstrated as occurring in the glasses, rather than one or the other. Is there an effort now to develop a more refined conceptualization (a single all-inclusive model) that can highlight these combined processes in the context of silicate glass dissolution behaviour?

Hi, interesting results. Just curious, have you thought about imaging the surfaces/interfaces of the glasses? Just to confirm the model based on your dissolution results? What were they to start of with? Powdered of smooth surfaces?
