Paolo Prampolini has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10858291
    Abstract: Ceramic tiles may be prepared employing a process characterized by the addition to the ceramic raw materials of an aqueous slurry comprising a swellable clay of the smectite family, a binder and a water-soluble salt of a monovalent cation. The ceramic raw materials mixed and then subjected to wet grinding to produce a slip. The thus obtained slip is then subjected to spray drying.

  • Patent number: 10190006
    Abstract: Method for decorating green or fired ceramic bodies by inkjet printing including the use of a ceramic inkjet ink which is prepared by milling a ceramic inorganic pigment in an organic medium in the presence of a dispersing agent which is the reaction product of a polyethyleneimine and a 12-hydroxystearic acid and ?-caprolactone co-polyester, until the average particle size of the pigment is between 0.1 and 0.8 ?m.
