Among the several issues that may arise along the glazing line, the excessive foaming within glaze suspensions is one of the most frequent and problematic. The phenomenon is already visible on the surface of the glaze inside the stirring systems but consequences can persist even after the end of...

Speaking of ceramic glaze applications and technical defects, one of the strangest and most interesting is the "TV effect". It consists of a preferential migration of the glaze towards the perimeters of the tile that produces in those areas a thickening of the glaze. The unaesthetic result is a...

Viscosity (or viscous friction coefficient) measures a substance attitude on generating friction between its layers. In other words, it defines the resistance of the fluid to its proper flow. The barbottina's viscosity values - that is the suspension of inorganic raw materials, water and...
