Abstract: A glaze composition can be used to provide a glaze layer having excellent antifouling performance and visual beauty. The glaze composition contains a glaze forming material, which has a composition determined such that a baked product obtained by baking the glaze composition comprises 55.0 to 67.0 wt % of SiO2; 8.0 to 11.0 wt % of Al2O3; 2.0 to 8.0 wt % of SnO2; 15.0 to 21.0 wt % of a divalent metal oxide; and 4.0 to 6.0 wt % of a monovalent metal oxide, with respect to a total weight of the baked product. When a glaze layer is formed by use of this glaze composition, it resists contamination. Even when a dirt deposits on the glaze layer, the dirt can be easily removed from the glaze layer. In addition, the glaze composition can provide a beautiful semi-opaque glaze layer with luster and a reduction in pore generation amount.

Abstract: A deodorant composition comprises an activated carbon, a binder, an argillaceous material, and a basic zinc carbonate. A deodorant is manufactured by the following steps: (a) a mixing step of the composition materials, (b) a kneading step to knead the mixture, (c) an extrusion to shape the kneaded mixture into a honeycomb structured solid or a powder, and (d) a drying step to remove moisture from the solid. The honeycomb structured deodorant has excellent odor absorption particularly for odors, hydrocarbons, and nitrogen oxides in vehicle exhausts.
