A glassy product in the form of granules obtained by melting special mixtures of raw materials (charge) in continuous fritt-melting furnaces.

A mixture of fritt with raw materials (kaolin, clay, dolomite, alumina, etc.), additives and water, ground to certain parameters and applied to a clay body in order to provide aesthetic and protective properties to the ceramic product after firing.
