A heating article includes a substrate having two opposite surfaces, at least one of which is opaque, and a heat-stable coating arranged on the opaque surface. The heat-stable coating includes an at least two-color decoration having continuous tones and being provided in the form of a continuous or discontinuous layer.

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 item (1) comprising a through-decoration (2) forming a so-called backlit plique--jour enamel, the method including obtaining a blank (5); removing part of the blank (5) from the inner face (5b) of the blank (5) to produce a decoration (2a) that does not pass through to the outer face (5a); depositing, from the inner face (5b), one or more layers of enamel (3) within the non-through decoration (2a); depositing, from the inner face (5b), a layer of luminescent material (4) on the enamel (3); depositing a protective layer (6) on the layer of luminescent material (4); and machining the outer face (5a) to reveal the enamel. Also, the related item.

A method for manufacturing an item (1) including a through-decoration (2) filled with an enamel (3) to form a plique--jour enamel. The method includes: obtaining a blank (5) defined with an upper face (5a) and a lower face (5b) opposite the upper face (5a); removing part of the blank (5) from the upper face (5a) to produce a decoration (2a) that does not pass through to the lower face (5b) or, alternatively, in the previous step, obtaining said blank (5) directly with the non-through decoration (2a); depositing one or more layers of enamel (3) within the non-through decoration (2a) and firing the enamel (3) after each 10 layer has been deposited; machining, preferably by grinding, the lower face (5b) to reveal the enamel (3) and thus produce the item (1) with the through-decoration (2) filled with enamel (3).

A method for engraving and texturing an item (1) including a decoration (2) filled at least partially with an enamel (3), the method including a laser ablation step using a femtosecond or picosecond laser on the surface of the enamel (3) and/or within the enamel (3) to produce a structure (7).

A construction material includes a base material. The base material includes a low-gloss region having a 60 gloss value of smaller than and a high-gloss region having a 60 gloss value of larger than or equal to 8. The 60 gloss value of the low-gloss region and the 60 gloss value of the high-gloss region are different from each other by 5 or greater.
