Abstract
A method for making glass and particularly ceramic frits, comprising the steps of: introducing in a wet grinding unit, after a metering step according to chosen proportions, materials which constitute a mixture to be melted, to produce a slurry; screening and collecting said slurry in a storage tank; introducing the collected slurry in a melting furnace to make a liquid component of the slurry evaporate; and forming a melted paste of vitreous material, adapted to be converted into a ceramic frit.

A method for making glass and particularly ceramic frits, comprising the steps of:
- introducing in a wet grinding unit, after a metering step according to chosen proportions, raw materials having a course particle size and natural moisture content and which have not been preliminarily dried or ground which constitute a mixture to be melted, and performing wet grinding unit in said wet grinding unit of said raw materials to grind said raw materials into ground particles of limited size to produce a slurry;
- screening and collecting said slurry in a storage tank;
- introducing and collected slurry in a melting furnace to make a liquid component of the slurry evaporate;
- and
- forming a melted paste of vitreous material, adapted to be converted into a ceramic frit.
