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.

According to an example aspect of the present invention, there is provided a tint base comprising titanium dioxide, a vehicle, and conventional additives, which tint base is capable of displaying a preselected colour upon the addition of a colorant, wherein at least 4% by weight of the titanium dioxide is present in the form of opaque aggregates of titanium dioxide and precipitated calcium carbonate particles wherein the titanium dioxide particles are at least partially encased by the particles of precipitated calcium carbonate.

The present invention provides a red paint for ceramic decoration, including a glass matrix, and a red colorant and a protective material that are intermingled in the glass matrix. The red colorant contains gold nanoparticles and silver nanoparticles. The protective material contains silica nanoparticles.

The present invention provides dissolvable films for customizing art materials, such as inks, paints, and modeling doughs. The invention also provides methods and kits for delivering artistic effects to art materials. The dissolvable films comprise one or more cellulose compounds, propylene glycol, glycerin, and one or more artistic components. The dissolvable film imparts an artistic effect following administration of the film to the art material. In exemplary embodiments, the artistic components of the film comprise one or more colorants which provide a coloring effect. A kit for delivering one or more artistic effects to an art material includes dissolvable films of various colors and shapes, and one or more art materials, such as ink, paint, or modeling dough.
