A method for producing engineered stone slabs including steps of depositing a composite material onto a supporting structure; disrupting the composite material using a plurality of stirring devices attached to a shifting structure; depositing colorant in a predefined region in the composite material using a spray device to form a colored disrupted composite material; and using a first device to press, flatten and stretch the composite material into a slab after disrupting and depositing colorant. The step of disrupting may occur before, after, or during the step of depositing colorant. The step of disrupting the composite material or the step of depositing colorant may include causing the shifting structure to move along a width of the supporting structure. Prior to depositing the composite material onto the supporting structure, and after compressing the composite material, the composite material may be fragmented into a plurality of fragments of composite material.

A plant for manufacturing ceramic articles comprising two feeding devices, each of which is configured to contain a powder material of a respective type and feed this powder material to a conveyor assembly. The plant further comprises an operating device, which is configured to allow the powder material to exit selectively from zones of the feeding devices arranged in succession crosswise to the movement direction, moving vertically and independently from one another a plurality of transfer moving parts, each provided with a transit channel through which the powder material moves to reach the conveyor assembly.

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.

A method of preparing a ceramic fabric for use in a ceramic matrix composite includes transforming a ceramic tow from a first tow geometry to a second tow geometry, thereby reducing a first dimension of the ceramic tow and increasing a second dimension of the ceramic tow orthogonal to the first dimension to produce a flattened tow. The method includes weaving or braiding the flattened ceramic tow to form a ceramic fabric.
