The lack of cohesion that occurs not only between the glaze’s particles but also between the glaze and the raw ceramic support can lead to a problem that is commonly called "dusting phenomenon". This kind of glaze, that we could define as fragile, is easily removable from the ceramic surface, especially when it undergoes to the mechanical solicitations that take place along the production line. 


The problem is particularly clear after the evaporation and draining process, when the glaze has definitely lost its solvent part (the liquid component, that is water). What happens inside the glaze and what can we do to prevent and to properly manage the problem?
