Abstract

During the production of the porcelain, the roughcast is fired at 1,300 deg. c for 8-10 hr; after cooling and being painted evenly with moderate and low temperature color glaze, it is fired for another 3-4 hr; and after cooling to 100 deg. c and being painted at craks with moderate and low temperature color galze of different color, it is fired for another 2-3 hr and then cooled. This kind of art porcelain looks like being covered by one color net and it has smooth hand feeling but certain 3-D effect.

Description

Porcelain with decorative color drawings and production method thereof

What the present invention relates to is art ceramics product and preparation method thereof, particularly ceramic flat surface net-like pattern product and preparation method thereof.

The magnificent pretty ease of China's ornamental ceramics has unique traditional style.From mid-term the Tang Dynasty so far, decorate to the five colours by monochromatic colored drawing, the development kind is more various, has become the garden with hundreds of flowers of the painted decoration that flowers blooming like a piece of brocade at present.Colored drawing is broadly divided under glazed and over-glaze decoration, and under glazed is that colorant is plotted on the biscuit of unfired, and then hangs up that the layer of transparent glaze is fired to form, and makes pattern on the porcelain facing, colored drawing clear, bright.As bright eternally happy, Xuande blue and white decorative ceramics in period, have abundant colors and change, deep or light bloom, go deep into the tire bone, the effect of ink and wash is arranged.Famous for another example " under-glaze red " is to draw pattern and be fired into reducing flame under glaze with the material of painting of copper, and as the Chinese traditional ceramics kind that shows unique characteristics, the implicit and graceful color that is presented is impayable.Over-glaze decoration then is to carry out polychromy with the colorant glaze on burned ground-coat enamel, then fires to form.Foremost traditional decoration, powder enamel and the colour enamels of surely belonging to, it is ornamental very strong, particularly colour enamels is thin a kind of of worker the most in the colored drawing, pursuit be exquisite careful, magnificent gorgeous.

The present invention provides a kind of colored drawing and sintering technology, can when over-glaze decoration the different color glaze be embedded hacking in the line of ground-coat enamel, and become the ceramic product of plane net glaze.

The method that the present invention recommended is: end tire was fired under 1300 ℃ 8～10 hours, cooling back with in, low temperature ground-coat enamel (can be any color) evenly coats, go into kiln in, fired 3～4 hours under the temperature of low temperature glaze requirement, be cooled to 100 ℃ of kiln discharges, the surface forms crackle naturally, cracks be coated be different from the ground-coat enamel color in, low temperature glaze, kiln-firing is 2～4 hours again, cooling promptly gets plane net glaze ceramic product.Employed two kinds of glaze all are the glaze that flow.Its plane of this plane net glaze product is smooth, and integral body resembles pottery and wraps with a bright net look, and is very attractive in appearance.Particularly can streakline very thick, its color can be selected arbitrarily.

Characteristics of the present invention are: (1) decorates webbed ceramics with color glaze is attractive in appearance and have the new meaning product, but particularly the net of any color all colored drawing and firing form, opening white net glaze as red line is the decorative porcelain that had not had so far.(2) sintering technology uniqueness, utilize fire, crackle appears hacking in process of cooling, inlays, infiltrates method in the ground-coat enamel with color glaze--in particularly using, cryogenic mobile glaze--makes feel smoothly and stereo netted glaze porcelain product are arranged.

Example 1

Behind the plain tire porcelain vase of making, it is gone into kiln, fired cooling, taking-up 8 hours in 1300 ℃, middle temperature white glaze brushing glazing with 1000 ℃, in 1000 ℃ of kilns, fired 4 hours, be cooled to 100 ℃ of kiln discharges, aging crack occurs, cracks with 1000 ℃ in warm red glaze along the line glazing, reenter kiln and under 1000 ℃, fired 2 hours, the cooling kiln discharge, the painted decoration pottery of the red net of white background.

Example 2

Sintering technology such as example 1, and be ground-coat enamel sky blue low temperature color glaze, and the cracks glazing is light brown low temperature color glaze, all fires under 800 ℃.Product is the light brown net of sky blue bottle.
