Abstract
In this second part, examples of glass pieces submitted to a leaching process are analyzed. A discussion is undertaken to show how to prevent secondary effects. It is pointed out how the near-surface region of the glass sample interacts with the surrounding aqueous solution, by testing three different glass compositions and various leaching solutions, and different leaching time and temperature. An increasing rate of the heaviest components of the glassy matrix, which is observed in almost all cases, is connected with the glass composition as well as with the solution composition. The strong leaching solution's pH value depends on ion-exchange and redox equilibria as main phenomena.
