Abstract: A method and machine for the surface decoration of a basic article comprising ceramic material and having a surface and a printing assembly applies an adhesive material digitally and selectively onto a defined area of the surface. A treatment assembly deposits a powder material digitally and selectively in the defined area, and the powder material in excess arranged on the basic article is removed.

Abstract: The invention relates to a chamber (2) for gas sensors (9) to be used in a device (1) for detecting aromas or odors. The chamber (2) comprises three portions (5, 6, 7) in which there is a uniform, turbulence-free flow (F) of gas or vapors to be analyzed, and at least one gas sensor (9) positioned in the central portion in such a way as to be immersed in and to laterally and tangentially interact with the flow (F). The chamber (2) also comprises a heating and temperature regulating device (16, 17). The invention also relates to an odor detection method which comprises a step in which a uniform, turbulence-free flow (F) of gas or vapor interacts with a gas sensor (9) laterally and tangentially.

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.
