Abstract

The present invention relates to pottery with a crazed glaze surface and a making method thereof. In the method, a thick layer of high-temperature glaze is smeared on a mud blank, and the mud blank is baked at a temperature of 1200 to 1300DEG C for 8 to 10 hours in a kiln; the temperature of the mud blank is cooled till the temperature reaches 100DEG C, and the cooled mud blank is taken out; when clefts appear on the glaze surface, middle or low temperature glaze is smeared along the cleft lines, and the mud blank is baked in the kiln for 2 to 3 hours; the baked mud blank is cooled till the temperature reaches the indoor temperature, and the pottery with a crazed glaze surface is obtained. Because the crazing is glazed two times, the crazing has different thicknesses, and therefore, the crazing has convex and concave streak lines and has cubic effect. The color of the glaze surface and streak lines of the crazing can be arbitrarily regulated, which makes a breakthrough on the Geware glaze in the history and the emulating articles, and the crazing of the Geware glaze in the history and the emulating articles only have few color varieties of brown or yellow or black. Ceramic handicraft articles of novel crazing with big difficulty degree such as black glaze white crazing are manufactured.

Description

Crackle glaze ceramic ware and making method thereof

The present invention relates to craft artistic pottery and porcelain product and preparation method thereof.

Pottery is one of greatness invention of China, and in the age, the working people createed various products with height artistic level and national style, and successively it is spread all over the world thousands of years long histories, and some treasure the presents handed down from ancient times are still by various countries' museum collection.Gradually river dragon's fountain brother kiln is one of Song dynasties five your name's kiln, its produce the celadon vessel that have crackle by generation treasure, much imitative in history product also are known as " brother's glaze ".Brother's kiln is to utilize to burn till in the process of cooling at pottery, and the shrinking percentage of glaze and tire is different, and glaze ftractures into defective in irregular texture-this technological process-and make unique product.Glaze crackle, paddy claim to hack: the glaze color is light, as off-white, cream colour, milk Huang, pale blue, grey green grass or young crops etc.; The then existing careless black of fault line has Huang, red microgroove again, is called " spun gold iron wire "; The vessel mouth is tawny, and foot is iron black look, also claims " purple mouthful iron foot ".This to have crackle (cracked ice pattern, roe line, ox hair line, crab claw line etc. are arranged) taxi driver brother's kiln pottery very unique, attractive in appearance, constantly has various imitations to occur in history, and as Song's government porcelain kiln, and the similar articles of Japan, Korea all is imitative brother's kiln product.Yet the glaze colours of brother's kiln product and imitative product and streakline color are relatively more dull, hack size and streakline thickness, the depth and all fail indiscriminately ad. as one wishes to regulate.

The invention provides a kind of new sintering technology, make the glaze and the streakline crackle pottery ceramic handiwork of multiple color, particularly can make the streakline depth adjustable, have the intensive stereoscopic sensation, make it beautiful and luxurious more.

As everyone knows, the pottery drawing can be behind once-firing, carries out the colored drawing secondary again and fires and form.Yet thinner band colo(u)r streak is difficult to burn at slick ceramic surface after burning till for the first time.The solution of the present invention is that high temperature color glaze is coated in thickening on unpainted clay idol, low temperature color glaze during coat on the streakline that splits the cooling back, twice firing versicolor hacking.Concrete grammar is: it is ground-coat enamel-high melting glaze of 0.5～1.0 millimeter that thickness is coated on the unpainted clay idol surface after doing, going into kiln fired under 1200～1300 ℃ 8～10 hours, slowly cooling, about 100 ℃, take out, treat that crackle appears in color glaze, immediately on the streakline of crackle upper edge for the second time color glaze-in or low temperature glaze, reenter stove in or fired 2～3 hours under the temperature of low temperature glaze requirement, slowly be cooled to room temperature and promptly obtain the art ceramics vessel that hack very attractive in appearance.On streakline for the second time during color glaze, on the colored glaze thicker the time then be fired into hack that to see its streakline be convex shape, otherwise streakline is and falls in shape must approach on the colored glaze time, has fairly obvious stereoscopic sensation.Because glaze colours can select, can be fired into always have never seen hack art pottery works, for example black porcelain is opened white etc.

Characteristics of the present invention are: (1) can make versicolor crackle pottery ceramic products, and this has just broken the restriction that historical light glaze is opened dark color (palm fibre, minority look such as black are only arranged) sheet; Particularly streakline can be fired into convex concave, plays relief brand-new effect, and this is the innovative product that pottery hacks art.(2) in utilizing in the sintering procedure on this overglaze fault location of cover-coat enamel crackle or low temperature glaze, make its embedding wherein and once more be fired into three-dimensional streakline, not only play stereo effect, and also have and do not fall constant characteristics for a long time.

Example

Mould bottle at a gulp with china clay.Place indoor in the shade put dried, bottle face last layer black high melting glaze, its thickness is 0.5～1.0 millimeter, fires in about 1300 ℃ 8 hours in stove.Take out to place when slowly cooling off 100 ℃, crackle appears in the glaze laminar surface, along streakline coated white medium temperature glaze, burns 2 hours in 1000 ℃ stove, slowly is cooled to room temperature, must have relief black glaze open white hack the art pottery porcelain vase.

Claims

1. pottery that the glaze solid is hacked, it is characterized by cracks at the cracked glaze of ceramic surface has and protrudes or the streakline of recessed random color; This pottery is to make according to the following procedure: fired high melting glaze on the base substrate is hacked, in the fault line place is coated with random color, low temperature glaze, fires once more and form; When color glaze is coated with thickly, is fired into the crackle that hacks and presents convex shape; When color glaze is coated with thinly, is fired into the crackle that hacks and presents recess-like.

2. a glaze solid is hacked ceramic making method, it is characterized by the high temperature of 0.5～1.0 mm thick color glaze is arranged on the exsiccant biscuit, in 1200～1300 ℃ of kilns, burnt 8～10 hours, be cooled to 100 ℃ of taking-ups, treat that crackle appears in glaze, in cracks is coated with random color, low temperature color glaze, reenter in the kiln in, fire under the temperature of low temperature glaze requirement and formed in 2～3 hours; Be coated with to such an extent that the thick fault line that hacks that then is fired into of color glaze presents convex shape on the streakline; Color glaze is coated with to such an extent that the thin fault line that hacks that then is fired into presents recess-like.
