Abstract
The invention relates to the technical field of porcelain making and in particular relates to a Runyu porcelain and a preparation method and a repair process thereof. The Runyu porcelain comprises the following components: kaolin, feldspar, high silica, soda lime, talc, zirconia, paraffin, a thickener, polyvinyl alcohol, a plasticizer and the like. According to the Runyu porcelain and the preparation method and the repair process thereof provided by the invention, due to the improvement of raw materials and control of the firing process, the Runyu porcelain is fired for at least two times, and the fired porcelain is mild in surface touch and has a hetian jade white color, so the porcelain is called the Runyu porcelain. The repair process is increased between an initial firing process and a re-firing process, and due to the process treatment, the yield of the Runyu porcelain can reach 99% or higher, the raw material cost can be saved, and the Runyu porcelain is energy-saving, environment-friendly and particularly suitable for making high-end artware.
Description
technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a jade-running porcelain and its preparation method and restoration process. Background technique [0002] White porcelain is one of the traditional Chinese porcelain classifications. It is fired with a low-iron content porcelain blank and coated with a pure transparent glaze. Existing white porcelain is made of its ceramic body which must pass through multiple processes such as inspection, polishing, washing, drying and glazing after bisque firing, and then "glaze firing" to produce ceramic products. [0003] High whiteness and high light transmittance have always been the criteria for evaluating high-quality white porcelain. For this reason, existing white porcelain producers often obtain better quality white porcelain products by changing the clay formula of traditional white porcelain, such as the patent No. 200910111290.6 The invention patent discloses a new t...
