Annular spot glazed ceramic and preparation process thereof
The invention relates to the field of ceramics and preparation processes thereof, in particular to an annular spot glazed ceramic and a preparation process thereof.The annular spot glazed ceramic comprises a green body and a glaze layer, the glaze layer sequentially comprises foaming makeup soil, ground glaze and cover glaze from bottom to top, and annular spots are distributed on the glaze layer. In the glaze firing process, foamed particles in the foamed makeup soil are decomposed to form gas, the gas rises to form foamed glaze, glaze bubbles break through a glaze surface to form glaze pits, ceramic mother liquor and other substances with good fluidity in the ground glaze fill the glaze pits, then ferric oxide around the glaze pits is enriched, and a red brown glaze ring deeper than the ground glaze in color is formed. A light yellow round spot is formed in the center of the glaze ring, namely an annular spot is formed; in the re-firing process, the cover glaze flows towards the glaze pit and fills and levels up the glaze pit, and radioactive cracks are formed around the glaze ring in the cooling process.
本发明涉及陶瓷及其制备工艺领域，具体涉及一种环状斑点釉面陶瓷及其制备工艺，环状斑点釉面陶瓷包括坯体和釉层，釉层从下往上依次包括发泡妆土、底釉和面釉，釉层上分布有环状斑点。釉烧过程中，发泡妆土中成泡颗粒分解形成气体，气体上升形成泡釉，釉泡突破釉面后形成釉坑，底釉中陶瓷母液等流动性较好的物质向着釉坑填补，进而导致釉坑周围的氧化铁富集，形成颜色比底釉颜色更深的红褐色釉环，釉环的中央则形成浅黄色圆斑，也即形成环状斑点；复烧过程中面釉向着釉坑流动并填平釉坑，降温的过程中釉环周围形成放射性裂纹。
