Description

A kind of celadon glaze color production process combining pottery clay and porcelain clay

technical field

The invention belongs to a celadon production process, in particular to a celadon glaze color production process in which pottery clay and porcelain clay are combined.

Background technique

Existing ceramics need to be glazed after bisque firing, and fired again after glazed, so that the appearance of the porcelain produced like this is single. It is an urgent desire of those skilled in the art to develop porcelain with more peculiar and novel appearance decoration effect.

Contents of the invention

The technical problem to be solved by the present invention is to provide a celadon glaze coloring manufacturing process in which pottery clay and porcelain clay are combined to address the deficiencies in the prior art.

In order to achieve the purpose of the present invention, the following technical solutions are adopted to achieve: a celadon glaze coloring manufacturing process combining pottery clay and porcelain clay, comprising the following steps in turn:

1) Forming:

a. First take a piece of clay, put it on a clean operating table, and knead it with both hands holding the clay and rolling to remove the air;

b. Put the kneaded clay into the center of the turntable of the drawing machine;

c. Start the machine, wet your hands, and knead the mud evenly from bottom to top and hold it up and down several times;

d. Stabilize the mud column, press the center opening of the mud column with your thumb to expand and lift, use both hands to cooperate inside and outside, the right hand assists the body outside, and the left hand slowly expands and lifts outward in the body;

e. Use the shape of the stencil in the rotation to perform the operation of leveling and adjusting the shape;

f. Put the kneaded porcelain clay into the drawn clay body, start the machine, press the porcelain clay inside the clay body with the palm of your hand, and fill the clay body with porcelain clay during rotation the entire surface;

g. Cutting the drawn green body with a cutting line and taking off the green body;

h. Place the finished green body on the green frame to dry slowly in the shade.

2), trimming:

a. Use a trimming tool to trim and scrape the remaining mud inside and outside the body of the utensil. First, remove the residual mud at the bottom of the body and supplement the mud at the defective part; then trim the remaining mud inside and at the mouth of the body mud;

b. Use a brush dipped in water to wash away the mud powder and knife marks left on the green body due to trimming, so that the green body can be smooth and complete;

3) Biscuit firing: put the dry body into the kiln car, push the kiln car, close the kiln door, and carry out low-temperature drainage firing, and the temperature rises from the kiln temperature to 750 degrees;

4) Glazing decoration: glaze the biscuit-fired body;

a. Choose celadon plum green glaze water, scoop the glaze water into the body and cover it, let it rest for 2 minutes, let the glaze layer absorb the body to a certain thickness, and then pour out the remaining glaze;

b. Put the green body in the sun for 2-3 hours to dry;

c. Use a sponge brush to clean the remaining glaze on the outside of the green body;

d. Then enter the thickening of the glaze spraying, scoop the glaze water into the glaze spraying pot, and spray the glaze on the green body until the required thickness of the glaze layer is completed;

e. Put the glazed body again in the sun for 2-3 hours;

f. Use a sponge to wash the glaze at the bottom of the green body;

5), kiln firing:

a. Put the glazed green body into the kiln car, close the kiln door, and ignite for firing;

b. Enter the low-temperature dehumidification stage, rising from room temperature to 950 degrees;

c. Enter the medium temperature stage, the temperature rises from 950 degrees to 1100 degrees, this stage is the heat preservation and reduction stage;

d. Entering the high temperature stage, the temperature rises from 1100 degrees to the firing temperature. This stage is a strong reduction stage, and the green body enters the porcelain conversion stage;

e. In the stage of flameout and cooling, the temperature is lowered from the firing temperature to room temperature.

Compared with the prior art, the beneficial effects of the present invention are: the main body shape of the device produced by the process of the present invention is reflected by direct washing, the clay part presents a simple, thick and rough feeling, and the celadon glaze part of the main body presents a fresh and delicate emerald appearance. Clear and moist, the main plane of the celadon glaze presents the effect of leaf patterns, showing that the veins of the leaves naturally extend to the depths of the corners, and go to the right angle to meet the edge of the mouth. You can see the gradient of the glaze color when you go to the veins. There is a feeling that the color of the celadon glaze is gradually fading. When it reaches the rim (the glaze layer is less than 85% of the main body), it presents the effect of sesame dots, and the reddish-brown sesame dots on the rim are in contrast to the appropriate tone of the khaki-brown block surface on the upper part of the rim. In comparison, the effect is very beautiful and miraculous. Judging from the effect of the glaze color of the three parts, there is an effect of mutual connection and echo.

It highlights the strong contrast effect between the rough ore and the fineness, which reflects the feeling of thick and elegant as a whole, and presents the elements of the combination of modern celadon and ancient culture. The presentation echoes each other to achieve a magical and natural style of ancient rhyme.

detailed description

As shown in Fig. 1, the present embodiment is a celadon glaze coloring manufacturing process combining pottery clay and porcelain clay, which includes the following steps in turn:

1) Forming:

a. First take a piece of clay, put it on a clean operating table, and knead it with both hands holding the clay and rolling to remove the air;

b. Put the kneaded clay into the center of the turntable of the drawing machine;

e. Use the shape of the stencil in the rotation to perform the operation of leveling and adjusting the shape;

f. Put the kneaded porcelain clay into the drawn clay body, start the machine, press the porcelain clay inside the clay body with the palm of your hand, and fill the clay body with porcelain clay during rotation the entire surface;

g. Cutting the drawn green body with a cutting line and taking off the green body;

h. Place the finished green body on the green frame to dry slowly in the shade.

2), trimming:

a. Use a trimming tool to trim and scrape the remaining mud inside and outside the body of the utensil. First, remove the residual mud at the bottom of the body and supplement the mud at the defective part; then trim the remaining mud inside and at the mouth of the body mud;

b. Use a brush dipped in water to wash away the mud powder and knife marks left on the green body due to trimming, so that the green body can be smooth and complete;

3) Biscuit firing: put the dry body into the kiln car, push the kiln car, close the kiln door, and carry out low-temperature drainage firing, and the temperature rises from the kiln temperature to 750 degrees;

4) Glazing decoration: glaze the biscuit-fired body;

a. Choose celadon plum green glaze water, scoop the glaze water into the body and cover it, let it rest for 2 minutes, let the glaze layer absorb the body to a certain thickness, and then pour out the remaining glaze;

b. Put the green body in the sun for 2-3 hours to dry;

c. Use a sponge brush to clean the remaining glaze on the outside of the green body;

d. Then enter the thickening of the glaze spraying, scoop the glaze water into the glaze spraying pot, and spray the glaze on the green body until the required thickness of the glaze layer is completed;

e. Put the glazed body again in the sun for 2-3 hours;

f. Use a sponge to wash the glaze at the bottom of the green body;

5), kiln firing:

a. Put the glazed green body into the kiln car, close the kiln door, and ignite for firing;
