A method of manufacturing a housing of an electronic device includes applying a mask to a portion of a ceramic green body to define a masked portion and an unmasked portion, applying a pigment to the ceramic green body to color the unmasked portion, and sintering the ceramic green body to remove the mask and form a ceramic housing. The ceramic housing may comprise a first portion corresponding to the masked portion and having a first color, and a second portion corresponding to the unmasked portion and having a second color different from the first color.

A cement-based tile formed from a mixture comprising: a cement in the range of about 0.1 to 88% by wet weight percent; a secondary material in the range of about 0.1 to 50% by wet weight percent, the secondary material comprising limestone, sand, silica sand, gypsum, silica fume, fumed silica, Plaster of Paris, calcium carbonate, fly ash, slag, rock, or a combination thereof; a reinforcement fiber in the range of about 0.5 to 20% by wet weight percent, the reinforcement fiber comprising cellulose fiber, glass fiber, plastic fiber, polypropylene fiber, polyvinyl alcohol (PVA) fiber, homopolymer acrylic fiber, alkali-resistant fiber, or a combination thereof; a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent; a water in the range of 10 to 60% of a total wet material weight; and wherein the mixture is extruded or molded to form the cement-based tile.

A method for manufacturing a bullnose tile comprising the steps of providing a ceramic tile that comprises a base body made of a ceramic material, wherein the base body has a main surface and a bullnose edge; providing a decorative layer on top of the bullnose edge by printing a curable ink to form a decor; and curing the curable ink; wherein the curable ink, after printing, is in direct contact with the ceramic material of the base body.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

A dispensing system for dispensing a slurry or glaze for making or printing products of the ceramic industry comprises a plurality of reservoirs suitable for containing a respective fluid mixture or glaze and at least one dispenser associated with the reservoirs and equipped with at least one outlet for dispensing the fluid mixture. The system further comprises at least one mixer operatively interposed between the reservoirs and the dispenser, and configured to receive the fluid mixture from each reservoir and to send a mixed fluid to the dispenser, adjusting means operatively interposed between each reservoir and the mixer, and a control unit associated with the adjusting means and configured to drive them so as to adjust the mixing ratio between the flow rates of fluid mixtures into the mixer depending on a reference signal related to a predetermined hue of the mixed fluid.

A technique is described for the application of three-dimensional (3D) relief to a substrate such as a ceramic tile using digital inkjet technology. In an example embodiment, the introduced technique includes application of binder ink to a portion of the surface of a substrate using a digital inkjet process. This binder ink forms a barrier layer which protects the portion of the surface of the substrate. Next, a brushing process is applied to remove unprotected portions of the substrate, thereby forming the 3D relief in the substrate.

The present invention describes a ceramic tile with raised patterns and a method for producing raised patterns on a ceramic tile that comprises printing one ink followed by printing a second ink characterised by being insoluble in the previous ink, so as to form a raised pattern with a height of 50 micrometres to 500 micrometres. Finally, the ceramic tile is fired at a maximum temperature of 850 C. to 1300 C.

A method and a plant (i.e., system or assembly) for manufacturing ceramic products comprising the steps of feeding a mixture of ceramic powders so as to obtain a powder material strip; compacting the powder material strip so as to obtain a compacted powder layer; acquiring a surface image of the compacted powder layer that reproduces the respective surface chromatic effects; processing said surface image so as to obtain a graphic decoration to be applied on the surface of the compacted powder layer that is coordinated with the respective chromatic effects in the thickness; and printing the graphic decoration on the surface of the compacted powder layer.
