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 describes nanocellulose-based nanomaterials and their incorporation process into composites. Specifically, the present disclosure comprises nanocellulose functionalization processes, promoting better dispersion and homogenization of the nanomaterial in composites, as well as improving physicochemical and mechanical properties. The present disclosure lies in the fields of Chemistry and Materials Engineering.

Described herein is a seed composition comprising seed with a number of coatings and mixed with amphiphilic compound and hydrogel forming agent. The resulting seed composition which may be dry, is a single product configured to be storage stable and, when broadcast to a site, acts to deter or kill localised plant growth around the seed as defined by the agrochemical activity if agrochemical is present. The seed composition also supports nutrient levels and hydration about the seed resulting in high levels of subsequent seed germination. Related methods of manufacture and use are also described herein.
