A method may produce a ceramic part with a mother-of-pearl effect, in particular for watchmaking. Such methods may include: forming a ceramic body; depositing a layer of an oxy-nitride component of the OxNy type on at least a portion of the ceramic body; and oxidizing at least a portion of the oxy-nitride layer, preferably by heating.

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.

Ceramics are capable of reducing color irregularities and uneven coating, hard to dissolve into glaze, and excellent in fixation. A water-based paint contains a coloring material, first cellulose nanofibers having a lignin content of 20 to 40 mass % and a water retention of 150 to 300%, and second cellulose nanofibers having a higher viscosity compared to the first cellulose nanofibers, and the water-based paint has a B-type viscosity of 600 cps or higher. Ceramic ware or glassware or the like having painting made on a green body of which surface is formed of silicic acid or silicate compound as a main component, with the water-based paint.

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 method for providing one or more sides or edges of a ceramic unit with decor may include the step of providing the ceramic unit. The ceramic unit may be made of a ceramic material and may include decor disposed on a main surface of the ceramic unit. The method may also include the step of acquiring an image of at least a portion of the decor disposed on the main surface of the ceramic unit. The method may also include the step of deriving decor for a side of the ceramic unit from the image. The method may also include the step of providing the decor on the side of the ceramic unit.

A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.

Tableware, utensil and a preparation method thereof are provided, the tableware includes a bowl body. The bowl body includes a side wall portion, the side wall portion is connected to a bowl bottom through an arc-shaped portion. A bottom of the bowl bottom is provided with a bowl seat; the side wall portion, arc-shaped portion, and bowl bottom form a first chamber with an upward opening, the bowl seat is in a circular shape to form a second chamber with a downward opening; a dipping layer, which is provided at a bottom of the bowl body and covers the bowl bottom and bowl seat. By performing a dipping treatment on the bowel bottom and bowel seat of the bowl body, a plastic dipping layer is applied to surfaces of the bowl bottom and bowel seat. The dipping layer has characteristics of low thermal conductivity and high friction coefficient.

Decoration method and machine for the surface decoration of a ceramic article; the decoration machine comprises: a conveyor device having a metal support structure and a belt to support and transport the ceramic article through a printing station at least circa 2 metres long; a printing assembly comprising a plurality of digital printing devices; a detection unit to detect a quantity correlated with the moving speed of the conveyor device; comprising a reference integral with the belt, a detector to detect each passage of the reference and a processing device calculating the time interval between successive signals from the detector; and a control unit to adjust the mutual operation of the different digital printing devices as a function of the quantity correlated with the moving speed of the conveyor device so as to apply a defined pattern on the surface of the ceramic article to be decorated.

The process for the decoration of ceramic manufactured articles, comprises at least the following phases of:supply of at least one ceramic medium(S) to be decorated having at least one exposed surface (Sa) and at least one laying surface (Sb) opposite each other;application by means of a first printer, preferably a first digital inkjet printer (4), of a water-repellent liquid (L) on the exposed surface (Sa) according to a predefined design (D);spreading of a water-based glaze (C) on the exposed surface (Sa), wherein the spreading is earned out by means of a dispensing device (5);application by means of a second printer, preferably a second digital inkjet printer (10), of at least one ceramic ink on the exposed surface (Sa) with a design which is coordinated to the predefined design (D).

A dispensing device for decorating ceramic tiles with granular or powdered materials that includes a main body and a dispensing channel arranged in the main body and provided with a longitudinal axis. The channel has an inlet and an outlet opening along with a suction means, provided to retain a part of granular or powdered material inside the dispensing channel to form an accumulation that obstructs the dispensing channel and prevents the flow of material. A suction opening is arranged in communication with the dispensing channel and with the suction means and has a filter, interposed between the suction opening and the dispensing channel. A ventilation portion, associated with the main body and connected to the inlet opening of the dispensing device has an outer surface that communicates with the environment as a determined pressure.
