Once-formed Dehua eggshell porcelain and preparation process thereof

The invention discloses once-formed Dehua eggshell porcelain and a preparation process thereof. The once-formed Dehua eggshell porcelain comprises a porcelain blank and a glaze, wherein the porcelainblank comprises the following raw materials: Dehua kaolin, Dehua knar clay, Dehua low-temperature stone, and Dehua quartz stone, and the porcelain blank is based on Dehua low-temperature stone and Dehua kaolin, and combined with knar clay and quartz stone. Because Dehua's knar clay is rich in organic humic acid, plasticity, viscosity and fluidity of blank slurry can be greatly increased, and a thin blank body after drying is hard, and cannot be deformed. The blank slurry is subjected to gypsum mold slurry-injection molding, a blank with a thickness of 0.5-0.6 mm can be obtained at one time, multiple blank-trimming is not needed, steps are simplified, and a success rate of preparation of the eggshell porcelain is improved. 一次成型的德化薄胎瓷及其制备工艺，一次成型的德化薄胎瓷，包括瓷坯和釉料，瓷坯包括以下原料：德化高岭土、德化紫木节土、德化低温石、德化石英石，瓷坯以德化低温石和德化高岭土为主原料，配合紫木
