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.

An iron oxide powder includes a porous structure having the diameter of from 0.3 μm to 2 μm, wherein the iron oxide powder has an aluminum content of from 10 mol % to 80 mol %.

A method may produce a ceramic part with a mother-of-pearl effect, in particular for watchmaking. Such methods may include: forming a ceramic body; depositing a layer of an oxy-nitride component of the OxNy type on at least a portion of the ceramic body; and oxidizing at least a portion of the oxy-nitride layer, preferably by heating.

The application generally relates to a process for producing variants of concrete exposed aggregate finish (EAF) based on selected ratios from local and import, fine and coarse aggregate components. In particular, the process allows a user to select the desired appearance of the end result exposed aggregate finish, by selecting a ratio of local vs import fine aggregate and/or a ratio of local vs import coarse aggregate. Thus, the process allows for the ability to create a spectrum of daily variations of overall concrete mixes in order to achieve daily end result exposed aggregate finish.
