A set of hollow clay-brick blocks having rectangular dimensional sizes of 231223, 231212, 231210, 11.51210.5, 231211 or 231211, and each brick block has at least one of exterior side that is ceramiclly glazed.

Roof tile for forming a roof covering, wherein the roof tile (1) comprises a ceramic body (8); wherein said ceramic body (8) is made of porcelain; and wherein the roof tile (1) further comprises a glaze coating (9), which is situated above said ceramic body (8).

A composite ceramic element is provided in which the individual ceramic elements are passed on rollers and fired in a kiln, glazed and subsequently secured together.

The present disclosure relates to a ceramic tile decorated with dry particles to give a three-dimensional pattern and a manufacturing method thereof. The manufacturing method comprises the steps of A: glazing a surface of a green body with a ground coat; B: decorating a surface of the ground coat of the green body to form a pattern; C: drying the green body; D: embellishing the green body with dry particles; E: spraying a protective glaze on the surface of the green body; and F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile decorated with dry particles. The manufacturing method can make the ceramic tile produced have a clear pattern, distinct layers, low glaze glossiness, a good non-slip effect, an obvious sense of dry particles, a strong three-dimensional effect, rich colors, and stable properties.

A method for manufacturing a ceramic tile may involve providing a green tile having at least a green body with an upper surface. At least a first surface covering may be provided on the upper surface of the green body. The green tile may be fired to obtain a ceramic tile having a surface structure on its upper surface. At least one sinking agent may be applied on the upper surface of the green tile before providing the first surface covering. The sinking agent may determine the surface structure.

Pre-fabricated, custom pre-designed, high-density engineered solid surface products, including countertops and other architectural surfaces such as vertical wall surfaces and decorative panels and a method of manufacture of unitary custom-fit interior and exterior engineered solid surface products that are stain resistant, moisture impervious, UV resistant, acid resistant, dimensionally stable, abrasion and impact resistant, and are glazed to produce unique decorative and utilitarian surfaces in a wide range of colors and textures, including artistic, one-of-a-kind works. The glaze surface includes exterior vertical edges on countertops and back-splashes that are continuous with the top surface color and design. Optional flaming (open flame treatment or flame painting) or texturing of the post-glazed surface produces in a wide range of finishes, including a leather-look finish for crazed glazes. The invention includes custom-glazed monolithic engineered solid surface products that do not require site cutting, as a result of the inventive process.

A printing material and process for producing dense glass-ceramic articles by additive manufacturing are provided. The printing material includes a glass fit that densifies to a degree that closely approximates the theoretical density before appreciable crystallization occurs. Densification without interference from a crystalline phase enables greater degrees of densification. Further heating of the sintered printing material induces crystallization to form glass-ceramic articles having a density approaching the theoretical density. The printing material and process enable production of high density glass-ceramic articles at modest process temperatures.

A composite ceramic element and method of firing clay or ceramic elements in a roller kiln, comprising the steps of passing a first ceramic element on rollers through the roller kiln, passing a second ceramic element on rollers through the roller kiln, and mating and securing the first and second ceramic elements together after passing each said ceramic element through the roller kiln.

A method for manufacturing a roof tile, wherein the roof tile comprises a ceramic body, which is made of porcelain, and is provided with at least one hole, which is present in at least said ceramic body; wherein the method comprises at least the steps of providing a body composition; pressing the body composition; and firing the pressed body composition, and wherein, for forming said at least one hole, before said step of firing, a recess is formed in the body in the form of a blind hole or a through hole.

A decoration line including a conveyor of the products on which to apply the enamel, at least a first enamelling machine of the spray type actuated by piezoelectric-driven nozzles suitable for applying, on the products transiting on the conveyor, at least one first substantially full layer of enamel of the vitreous type in suspension in liquid suspending agent suitable for being processed in a digital decorative system for creating base or a covering layer on the products and at least a second enamelling machine, positioned downstream of said first machine, of the spray type actuated by piezoelectric-driven nozzles suitable for applying, on the products transiting on the conveyor, at least a second substantially discontinuous layer of enamel of the vitreous or pigmented type in suspension in liquid suspending agent suitable for being processed in a digital decorative system for creating decoration or finishing effects on the products.
