Longquan Ge kiln hundredfold crackle glaze and firing process thereof

Abstract

The invention discloses a Longquan Ge kiln hundredfold crackle glaze and a firing process thereof. A dry material of the hundredfold crackle glaze comprises, by weight, 30-50 parts of a blank, 12-25 parts of a glaze material, 15-25 parts of Linggen glaze soil, 15-25 parts of Huantang glaze soil, 1-3 parts of Zijin soil, 1-2 parts of plant ash and 5-15 parts of quartz. The firing process comprisesthe following steps: S1, manufacturing a green body; S2, preparing glaze slip: finely refining and uniformly mixing the glaze, adding water, carrying out ball milling until the fineness is 100 meshes,and filtering to obtain the glaze slip; S3, firing the green body, and glazing: preparing a porcelain blank from the green body, drying, then biscuiting, removing dust and powder from the obtained porcelain biscuit after drawing, and carrying out internal and external glazing; and S4, firing: putting the glazed biscuit into a kiln, and respectively performing four stages of firing to make the biscuit subjected to drying, oxidation, reduction, porcelain formation and heat preservation. The hundredfold crackle glaze fired by adopting the process is small in glaze surface cracking and is similarto hundredfolds in a staggered and overlapped manner, or large flakes exist firstly, so that the hundredfold crackle glaze is strong in stereoscopic impression and has a glittering and translucent visual effect.

Description

technical field [0001] The invention relates to the technical field of ceramic glaze and its firing, in particular to a Longquan Ge kiln rubbish broken glaze and its firing process. Background technique [0002] Ming Lushen's "Chunyutang Essay": "The elder brother's kiln is light white with broken lines, and the number is a hundred pieces of rubbish. Song Shizhang gave birth to the first and second brothers, both from Chuzhou, and mastered the Liutian kiln in Longquan. He gave birth to two pottery and green wares, pure Such as beautiful jade, which is the most precious in the world, that is, official kilns and the like. The pottery that produces a pottery is light in color, so it is called Ge Kiln." Zhejiang Longquan Ge Kiln is one of the five famous kilns in the Song Dynasty in China. The glaze is covered with cracked patterns. , usually called "open piece", it is the unique decorative style of Longquan Ge kiln products, and the celadon vessels with cracks produced are trea...

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 brother kiln mud or use external forces such as cold water after firing to form. The Ge kiln ice crack products obtained either have large pieces or small pieces, which cannot achieve the effect of small pieces and overlapping overlapping like rubbish, or there are large pieces first, and there are small unequal cracks in between. Three-dimensional, lack of crystal clear effect
