Description
Technical field
The present invention relates to a kind of glaze, and in particular to a kind of blue glaze of golden spot.
Background technology
Pottery is one of five big kiln porcelain of China's Song Dynasty, the treasure in Chinese tradition technology in producing porcelain, with unique transmutation
Art and be renown far and wide in generation, be the exclusive national treasure porcelain in Henan Province Xuchang Yuzhou City god Hou towns." blue glaze " its glaze colours in pottery is blue
Such as deep-sea, glaze is uniform, in colour-stable, but the blue glaze glaze colours that the existing glaze formula and firing process for firing blue glaze burns out
Single, glaze is without golden spot.
The content of the invention
The purpose of the present invention is that provides a kind of golden spot blue glaze to solve the deficiencies in the prior art.
The purpose of the present invention is realized with following technical proposals:
A kind of blue glaze of golden spot, it is prepared from by the raw material of following parts by weight:62-68 parts of melilite, 10-16 parts of quartz, side
Solve 12-18 parts of stone, 1.5-2.5 parts of tin oxide, 0.5-1.5 parts of spot fossil, 0.5-1.5 parts of bovine bone powder, 1.5-2.5 parts of talcum, orchid
0.5-1.5 parts of powder.
The blue glaze of above-mentioned golden spot, wherein, it is prepared from by the raw material of following parts by weight:65 parts of melilite, quartz 13
Part, 15 parts of calcite, 2 parts of tin oxide, 1 part of spot fossil, 1 part of bovine bone powder, 2 parts of talcum, blue 1 part of powder.
The blue powder is by cobalt oxide with local soil type of Datong District into the mass ratio of the cobalt oxide and Datong District's soil is 1:(9-11).
The blue powder is calcined 4-6h at 1150-1250 DEG C after cobalt oxide and Datong District's soil mixing and formed.
The preparation method of the blue glaze of above-mentioned golden spot, wherein, comprise the following steps:
(1)Above-mentioned raw materials are added water mixing, ball milling obtains glaze slip;
(2)Glazing;
(3)Burn till, firing temperature is 1240-1280 DEG C.
The preparation method of the blue glaze of above-mentioned golden spot, wherein, step(3)Middle firing process is comprised the following steps that:After glazing
Base substrate be put into kiln, temperature is ramped up 1240-1280 DEG C in 2-3h;It is warming up to after 1240-1280 DEG C and starts cooling,
First 750-800 DEG C is cooled to 6-8 DEG C per minute;Then room temperature is naturally cooled to.
The preparation method of the blue glaze of above-mentioned golden spot, wherein, the firing atmosphere burnt till is oxygen atmosphere.
The present invention is using melilite as primary solvent, and melilite compares for example white feldspar of other feldspars, red feldspar, silicon, iron content
It is higher, the glossiness of pottery jade glaze can be improved, and also iron content is high, it is easier to and the formation of golden spot, calcite plays hydrotropy,
Quartz can improve the mobility of glaze, and tin oxide is assistant toner, and spot fossil is a kind of poor iron ore containing iron oxide, be cosolvent and
Colouring agent, cyan can be showed and go out cash spot, the main calcic of bovine bone powder and phosphorus by being fired under high temperature and certain atmosphere, can be carried
The opacity of high glaze, talcum is natural hydrous magnesium silicate mineral, is the cosolvent of glaze, by increasing capacitance it is possible to increase the opaque of chun glaze;It is blue
Powder is burnt till under the native high temperature of cobalt oxide and Datong District, is also a kind of colouring agent.Melilite, calcite, quartzy spot in the present invention
Fossil originates from Yuzhou.
The present invention compared with prior art, by scientific and reasonable raw material proportioning and control burning process, has prepared glaze
Face has the blue glaze of golden spot, has filled up blank of the blue glaze without golden spot, is that blue glaze pottery adds a new varieties, and utilize
The gorgeous jade-like stone profit of the blue glaze of golden spot that the present invention is prepared, glaze is pin-free, lack the situation of glaze, and firing temperature is easy to control, yield rate
Height, up to more than 90%.
