CN111825429A - Preparation method of dotted crystal black pottery - Google Patents

Abstract

The invention discloses a preparation method of a point crystal black pottery, which comprises the steps of selecting high-quality yellow clay to be made into a green body shape, and selecting high-quality plant corn stalks as smoking materials; selecting copper oxide yellow, copper oxide purple, copper oxide red, iron oxide, aluminum oxide, zirconium oxide, germanite and cinnabar, respectively adding yellow clay, uniformly stirring, adding water to prepare slurry, dotting the prepared slurry into patterns according to the required colors of different patterns carved on the pottery, then placing the patterns into a kiln for firing, smoking by using plant corn straws, polishing a blank taken out of the kiln by using soft gauze until the metallic luster of the patterns is exposed, dotting the patterns on the blank by using liquid prepared from temperature-sensitive color-changing powder and styrene-acrylic emulsion, and drying in a drying chamber for 8 hours to obtain a finished product. Because the metal cluster can change color according to the temperature change by carrying out the treatment once again according to the requirement of art design, more art infectivity of the works is increased. The method can be used for preparing the dotted black ceramic product, has more excellent quality and is more suitable for viewing and collection.
