Abstract

Glaze application is the phase in a productive process that is more conditioned from the rheological properties of the glaze itself. During the preparation step in the mill, at moderately high temperatures (60-70°C), reactions between frits and the aqueous medium can occur and consequently begin the leaching of glassy network and the diffusion of the modifying ions through the leached frit layer. In the industrial process, variations on the pH and the ionic strength of glaze suspensions happen during the milling. Consequently changes on the rheological parameters (apparent viscosity, yield point, thixotropy) of glaze suspensions will verified. It is important to control these variables for keeping unaffected the aesthetic characteristics of the final products, after firing.
