Abstract
Disclosed is an article provided with a glaze layer having a mat tone surface having excellent texture. This article is provided with a substrate and a glaze layer provided on the surface of the substrate. The 60° glossiness of the surface of the glaze layer is greater than 20 and equal to or less than 50. The article has properties such that: the coefficient of variation of the root mean square slope (RΔq) of the roughness curve is 0.4-1 inclusive which is obtained by using a stylus type surface roughness measuring device according to JISB0651(2001) under a condition separately specified in JISB0601(2001); and the arithmetic average roughness (Ra) is 0.0-0.5 μm inclusive. The article has softness and warmness, is sensed to be moisturized and have high quality, and has improved touch feeling.
