The processing technology comprises the following steps that firstly, jiggering is carried out; secondly, blank printing is carried out, wherein a blank aired to be medium dry is put on a model mold in a covering mode, the outer wall of the blank is evenly pressed and patted, and mold releasing is carried out; thirdly, fine trimming is carried out on the blank, wherein the blank is put on a trimming barrel of a jigger in a covering mode, a jigger tray is rotated, and rotary cutting is carried out with a knife; fourthly, the blank is dried in the sun, wherein the processed and formed blank is arranged on a wood frame to be aired; fifthly, engraving is carried out, wherein a cutter made of bamboo or bone or iron is used for engraving patterns on a dried blank body; sixthly, glazing is carried out, wherein glaze slip is applied to the surface of the formed ceramic blank body; seventhly, baking in a kiln is carried out, the ceramic product is put into a sagger, the baking time in the kiln is 21-24 hours, and the temperature is 1,200-1,300 DEG C; eighthly, colored drawing is carried out, wherein pattern drawing and color filling are carried out on the glaze face baked into porcelain, the ceramic product is then put into a decorating kiln to be kilned at the low temperature which is around 720-790 DEG C; ninthly, the kiln is opened, after natural cooling is carried out for 12-18 hours, the kiln can be opened when the temperature in the kiln is lowered to the room temperature. The ceramic product processed through the technological method is high in finished product rate and good in glossiness, and benefits are increased for manufacturers.

Description

A kind of complete processing of ceramics

Technical field

The present invention relates to field of artware, be specifically related to a kind of complete processing of ceramics.

Background technology

Artwork, namely by the product that raw material or work in-process process by craft or machine, is the general name one group being worth to artwork.Artwork derives from life, but creates the value higher than life.It is people's crystallizations of wisdom, has fully demonstrated creativeness and the artistry of the mankind, is the priceless treasure of the mankind.

And ceramics is more subject to the favor of people, the working method for ceramics in prior art is improper, causes the ceramics fraction defective that processes high, brings unnecessary loss to manufacturer.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of complete processing of ceramics, the ceramics yield rate that this working method processes is high, reduces unnecessary loss.

Object of the present invention carrys out specific implementation by the following technical programs:

A complete processing for ceramics, comprises the following steps:

1) throwing: take porcelain stone from mining area, first with cobbing to the bulk of egg size, then break into powdery, eluriate, removing impurity, makes the clod of bricked after precipitation, and then is in harmonious proportion clod with water, remove slag, with the hands crumple, the air extrusion in walk out, and make the uniform moisture in mud, walk is fallen the center of turntable of throwing at jigger wheel, freehand method bend and stretch the roughly apperance that folding and unfolding draws out base substrate;

2) hand-pressing: overlaying in mould kind by drying in the air to half-dried base, evenly pressing and clapping base substrate outer wall, the then demoulding;

3) sharp base: covered by base and be put on the sharp bucket of jigger wheel, rotates hull, uses cutter rotary cut, makes base substrate thickness suitable, bright and clean in table;

4) base is shone: the base after machine-shaping is placed in airing on yoke;

5) texturing: depict decorative pattern with bamboo, bone or cutter made of iron on dry base substrate;

6) glazing: impose glaze slip on shaping ceramic body surface;

7) firing: ceramic is loaded saggar, kiln time is 21-24 hour, and temperature is at 1200-1300 °;

8) colored drawing: describe grain pattern in the glaze paint of burning till porcelain, fill out coloured silk, reenters red stove and burns baking with low temperature, temperature about 720-790 °;

9) open kiln: through the naturally cooling of 12-18 hour, when temperature is down to normal temperature in kiln body, can kiln be opened.

The complete processing of a kind of ceramics of the present invention, the steps include: throwing-hand-pressing-sharp base-solarization base-texturing-glazing-firing-colored drawing-open kiln, the ceramic yield rate adopting above-mentioned processing method to process is high, and glossiness is good, to manufacturer's improve effects.
