Abstract

The invention discloses a firing method of a black gold glaze built cup. The firing method comprises the following steps: preparing a green body and glaze slip, and glazing; and putting the glazed andair-dried green body into an electric kiln for roasting, powering off and stopping the kiln after roasting, naturally cooling, cooling and discharging. The raw ore is matched with other natural materials to prepare the green body and the glaze, the components are simple and pure, an innovative firing mode is adopted, the black gold glaze built cup is obtained, and the black gold glaze built cup is green black at the edge of the glaze built cup, and the other parts are black like paint, fine, mild, clean and bright as a mirror. And a small amount of oil drop crystals are hidden under the glaze(forming under-glaze drops), so that the product has unique artistic aesthetic feeling.

Description

technical field [0001] The invention relates to the technical field of porcelain, in particular to a firing method for a Wujin glazed Jianzhan. Background technique [0002] Jianzhan, the representative of black porcelain, is known as the "black pearl" on the crown of porcelain, one of the eight famous porcelains of the Song Dynasty in China, and was used by the royal family in the Song Dynasty. So far, it still attracts the attention of many consumers and ceramic collectors at home and abroad. [0003] Wujin glazed Jianzhan has a black and oily glaze surface and is mostly fired with firewood in a dragon kiln. It is not easy to control, it is difficult to find high-quality products, and the yield of finished products is very low (often less than 10%). Contents of the invention [0004] The object of the present invention is to provide a firing method for Wujin glazed Jianzhan, which is easy to control and implement, and the glaze surface of the fired Jianzhan is black and...
