Description

A kind of bronze green crystal glaze and method for cooking

(1) technical field

The present invention relates to a kind of bronze green crystal glaze, and use this glaze to fire the method for bronze green crystal glaze.

(2) background technology

Painted on the surface of ceramic, glazing is a kind of effective means that increases ceramic texture and aesthetic feeling, and the artistic effect that each glaze colours or pattern rose is different, various glaze colours, pattern or its combination are arranged in the market, and this mainly is to develop according to the demand in market.Have a kind of Gu that returns to return very on the Vehicles Collected from Market, pursue the general mood of nature, many things are particular about is a kind of simpleness, generous artistic effect.Naturally no exception for ceramic industry.Verdigris color can be given a kind of time immemorial of people, long, generous, simple sensation, if its pattern is made on the surface of ceramic utensil by the form of muffle painting, be to make the human consumer feel to have the dense Gu Zhiwei that returns, but in retrieval, find no this type of bibliographical information.

(3) summary of the invention

The object of the invention provides a kind of bronze green crystal glaze and method for cooking thereof with strong simple and honest artistic effect.

The technical solution used in the present invention is:

A kind of bronze green crystal glaze, its raw material mass mixture ratio is as follows; 20～25 parts of potassium felspar sands, 8～10 parts in calcite, 2～5 parts of kaolin, 4～8 parts of aluminium sesquioxides, 1～5 part of ventilation breather, 0.5～2 part of titanium dioxide.

Preferably, its raw material mass mixture ratio is as follows: 21.99 parts of potassium felspar sands, 9.23 parts in calcite, 3.40 parts of kaolin, 5.38 parts of aluminium sesquioxides, 2.00 parts of ventilation breathers, 1.4 parts of titanium dioxide.

The invention still further relates to a kind of method of using described glaze to fire bronze green crystal glaze, described method comprises: described glaze is mixed according to mass ratio 100:70～80 with water, and sink-float, sieve (100～300 order) gets glaze slip; Transferring glaze slip proportion is 1.51, glazes on the ceramic body, and electrical kiln is fired, and cooling obtains the ceramic that there is bronze green crystal glaze on the surface.

Preferably, to fire program as follows for described electrical kiln:

Fs: be warmed up to 150 ℃, time 150min from 20 ℃;

Subordinate phase: be warmed up to 300 ℃, time 100min from 150 ℃;

Phase III: be warmed up to 800 ℃, time 200min from 300 ℃;

Quadravalence section: be warmed up to 1240 ℃, time 240min from 800 ℃;

Five-stage: be warmed up to 1250 ℃, time 20min from 1240 ℃;

The 6th stage: 1250 ℃ are incubated 10 minutes.

Beneficial effect of the present invention is mainly reflected in: according to glaze formula of the present invention and method for cooking, can access the bronze green ceramic products with strong simple and honest artistic effect, and exquisite attractive in appearance; Prescription is simple, and easy to operate, cost is low.

(4) embodiment

The present invention is described further below in conjunction with specific embodiment, but protection scope of the present invention is not limited in this:

Embodiment 1:

Glaze quality prescription: 21.99 parts of potassium felspar sands, 9.23 parts in calcite, 3.40 parts of kaolin, 5.38 parts of aluminium sesquioxides, 2.00 parts of ventilation breathers, 1.4 parts of titanium dioxide mix.

Method for cooking: after above-mentioned batching is mixed, mass ratio according to glaze, porcelain ball milling ball, water is 1: 2.5: 0.8, about ball milling 50 hours, then glaze slip to cross the aperture be Φ 0.061mm(250 order) sieve, tailing over 0.02%～0.06%, can to change drainer over to for subsequent use.Glazing; Be Φ 0.154mm(100 order with the aperture again before the glazing) sieve filter, in sieve, put into the suction iron staff, glaze first through inhaling the iron staff deironing through the filtration of sifting out, elimination body refuse and impurity, it is 1.51 that glaze slip transfers to proportion, clean the dust on ceramic body surface before the glazing with clear water, the glaze layer thickness is 0.8mm.

Electrical kiln burns till: base substrate is put into kiln, and the fs burns 150 ℃ from 20 ℃ by 150 minutes, removes the moisture in the base substrate; Subordinate phase burns 300 ℃ from 150 ℃ by 100 minutes, and moisture eliminates; Phase III burns 800 ℃ from 300 ℃ by 200 minutes, makes base substrate stable; The quadravalence section burns 1240 ℃ from 800 ℃ by 240 minutes, makes the abundant melting of glaze; Five-stage burns 1250 ℃ from 1240 ℃ by 20 minutes, is incubated 10 minutes, and the glaze crystallization is fully finished.Then naturally cooling, by the time 100 ℃ can kiln discharge.

Finally obtain the glaze effect: glazing effect has the smooth glaze of inferior light, and color has the green crystal effect of unearthed bronze work, simple and unsophisticated atmosphere, and some place of glaze can be mingled with a small amount of brown crystallization spot and have more elegant effect.Be fit to make large property sight vessel.
