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.

The present disclosure applies to the production of ecological paints, which uses mineral pigments obtained from iron ore mining waste and tailings, transforming them into useful and sustainable products. The paints produced are free of volatile organic compounds (vocs), in line with international regulations and demands from conscious markets.

Provided is a water-soluble sheet-like coloring material in which sheets are less likely to stick to each other, have appropriate self-standing property and flexibility, and can be quickly brought into a uniform state when dissolved in water. A water-soluble sheet-like coloring material including a film-forming water-soluble polymer; a dissolution accelerator; a colorant; and a moisture-retaining agent.
