Abstract

The present invention relates to a ceramic handicraft of multi-color network glaze. High-temperature glaze is firstly manufactured into split sheets, and high-temperature glaze of the other color is coated on grain lines; the melting temperature of the high-temperature glaze used on the grain lines is slightly higher than that of the glaze for the split sheets by 5 to 10 DEG C, and the ceramic handicraft is burnt and prepared at the melting temperature of the high-temperature glaze for the split sheets after entering a kiln. The multi-color network glaze is vividly covered on ceramic products of different colors like a color network.

Description

Ceramic handiwork with coloured netted glaze and method for making thereof

The invention belongs to ceramics and method for making thereof, the ceramics of particularly colorful net glaze and method for making thereof.

Have the ceramic less of netted decorative pattern, wherein many firing with colored drawing forms.The crackle pottery porcelain utensils surface crack that China's Song dynasty Zhejiang brother's klining system forms (as cracked ice pattern, roe line, crab claw line) is commonly called as the spun gold iron wire, irregular network effect is seemingly arranged, but do not have clear reticulated structure, particularly its dull coloring.The technology that CN94100767.7 provided then can be made into the versicolor art ceramics that hacks, and has the relief artwork of recessed or protrusion, does not also have reticulated structure.The described plane net glaze of CN94100766.9 is to utilize the technology of hacking, and successively make and hack with high, medium temperature glaze, and streakline burns till car face color screen glaze pottery with medium temperature glaze.This net glaze is lived with the guard of a different colours just as an exquisite ceramics.Yet this reticulate pattern road is even, as drawing, and does not have the effect of " work ".

The objective of the invention is to be fired into color screen glazed ceramic handiwork with " work " net with a kind of new sintering technology.

The principle that the present invention realizes is: all with mobile high melting glaze as cracked glaze and streakline glaze, but temperature of fusion difference, streakline hacks with glaze slightly high (5～10 ℃) with the glaze ratio, the mobile netting twine that drives of cracked glaze flows when firing, and does not disorderly reach the effect of net " work " owing to its yield temperature height netting twine when flowing.Specific practice is: hang one deck high temperature color glaze on greenwave, thickness is 0.5～1.0mm, go into kiln and under 1300 ± 5 ℃, fire 4～6h, be cooled to 100 ℃ of kiln discharges, crackle occurs hacking, coat with another color high melting glaze at the streakline place, its temperature of fusion is a little more than 5～10 ℃ of the high melting glazes that hacks, reenter kiln then, degree of firing 2～4h under 1300 ± 5 ℃, the cooling kiln discharge forms.Because flowing of cracked glaze, and mobile ununiformity on every side, influencing streakline--the inhomogeneous of netting twine flowed, so the net on pottery surface is inhomogeneous attitude, have close have thin, particularly seem heap ground together at the lower edge of pottery selvage, whole pottery has played the effect of " work " net just as covering truly thereon with a look net.This sintering technology can be allocated arbitrarily and use different color glaze, thereby can burn till unprecedented, unusual exquisite various colorful net glaze alive.

The present invention compares the characteristics that have with background technology: the ceramics of (1) this net glaze alive is innovated, and is not only unprecedented in history, and has the characteristics of " work " with modern net glaze ratio, and more true to nature, more exquisite effect is arranged.(2) technology of utilizing the gap of cracked glaze and streakline glaze yield temperature to fire is very effective and peculiar.

Example one

Be coated with on the greenwave with black high melting glaze (1300 ℃ of temperature of fusion), thickness 0.5～1.0mm, go into kiln and fire 4h at 1300 ± 5 ℃, cooling is opened kiln at 100 ℃, crackle appears in the pottery surface, in cracks coated white high melting glaze (1310 ℃ of temperature of fusion), kiln-firing 2h reduces to room temperature and gets white with black net glaze goods again.As seen netting twine is with hacking the inhomogeneous mobile state of doing, and net has to dredge to be had closely, and net is like greater than pottery bottom, and shape pile together appears in its edge.

Example two

Method such as example 1, the cracked glaze that do not exist together be with white high melting glaze (1290 ℃ of temperature of fusion), and streakline burns out the net glaze alive of the red net of white background with red high melting glaze (1300 ℃ of temperature of fusion).

Claims

1, a kind of netted glaze ceramic handiwork, it is characterized by colorful net glaze, be by first mobile high melting glaze the pottery surface to be fired into to hack with a kind of color, another color that is higher than cracked glaze with temperature of fusion high melting glaze that flows is made the streakline glaze then, the method of under cracked glaze mobile temperature, firing once more and making, its structure is: the pottery surface is made up of the reticulate pattern line that hacks with different colours, because cracked glaze flowing when firing, its reticulate pattern line is inhomogeneous shape, have dredge have close, and there is the reticulate pattern line to pile up in the vessel lower edge, makes whole reticulate pattern present " the net effect of living ".

2, a kind of method for making of netted glaze porcelain technology, it is characterized by with the high melting glaze that flows as cracked glaze and streakline glaze, its technology is: hang one deck high temperature color glaze on greenwave, thickness is 0.5～1.0mm, goes into kiln and fire 4～6h under 1300+5 ℃, be cooled to 100 ℃ of kiln discharges, crackle appears hacking in ceramic surface, and the streakline place coats with another color high melting glaze, and its temperature of fusion is higher than hacks 5～10 ℃ of high melting glazes, reenter kiln and fire 2～4h in 1300+5 ℃, be cooled to room temperature and form.
