Preparation method and glaze of Longquan Ge kiln hundred waste broken porcelain

Abstract

The invention discloses a preparation method and a glaze for Longquan Ge kiln hundred-waste broken porcelain. The glaze is composed of the following components by weight: 16 parts of limestone, 20 parts of potassium feldspar, 8 parts of talc, 15 parts of quartz, fluorite 5 parts of stone, 27 parts of Qingtian stone, 6 parts of purple gold soil, and 3 parts of calcium. The preparation method is as follows: respectively take 25-35 parts by weight of purple gold clay, 5-15 parts of kaolin, 5-15 parts of alumina and 45-60 parts of porcelain clay, add an appropriate amount of water and knead into blanks, and then make blanks; The glaze slurry is obtained by mixing the raw materials with water and ball milling to obtain the glaze slurry; drying and bisque firing of the green body, and glazing after leaving the kiln; gradually heating the green body to 1200-1290 ℃ in the kiln, turning off the kiln fire, opening the kiln door, and using The blower quickly reduces the temperature of the kiln to 500-600°C for 20-30 minutes, closes the kiln door and turns off the blower, and takes out the rubbish and broken porcelain after natural cooling. The rubbish broken porcelain made by the invention has the advantages of obvious texture features, smooth touch like jade, crystal clear appearance and strong three-dimensional effect.

Description

technical field [0001] The invention relates to a glaze of Longquan Ge kiln hundred-waste broken porcelain and a preparation method of Longquan Ge kiln hundred-waste broken porcelain. Background technique [0002] Ming Lu Shen's "Chunyutang Essays": "Ge kiln is white and broken, and the number is 100 rubbish. In Song Dynasty, Zhang gave birth to one and two brothers, all of whom were from the prefecture, and mastered the Liutian kiln of Longquan. Such as beautiful jade, which is precious in the world, that is, official kilns and the like. The color of a pottery is pale, so it is called Ge kiln." Zhejiang Longquan Ge kiln is one of the five famous kilns in the Song Dynasty in China, and its glaze is covered with cracked patterns. It is the unique decorative style of Longquan Ge kiln products, and the cracked celadon ware produced is treasured by the world. The so-called "opening" means that the thermal expansion coefficients of the green body and the glaze are different, and...

Problems solved by technology

[0004] However, because the firing technology has been lost for a long time, it is extremely difficult to burn the rubbish in the Longquan Ge kiln, and the yield is extremely low. At present, many producers use the mud of the Ge kiln and then use external forces such as cold water to form it. Ge kiln ice cracked products are either large or small, and have a cut feel when touched, which cannot achieve the effect of ancient rubbish. The existing technology cannot reflect the texture like fish scales and fish roe, and lacks three-dimensionality. Lack of crystal clear effect
