[Must Learn Skills] Ten Processes of Ceramic Painting Making

Ceramics are various products made of natural clay and various natural minerals through crushing, mixing, molding and calcination. In the past, people called things made of clay and fired in special kilns ceramics. Ceramics have a good decorative effect, and the ceramic paintings that have emerged in recent years have also been welcomed by many people. Let's take a look at the process of making ceramic paintings.

Production technology of ceramic painting

1. Clay kaolin is the best raw material for firing porcelain. For thousands of years, many exquisite ceramics have evolved from these humble porcelain clay. The first process of making porcelain: clay is to make porcelain clay into usable porcelain clay.

Second, the porcelain clay washed out by that pile of mud can't be used immediately. It should be stored and drawn separately in columns.

Third, draw a blank. Put the folded porcelain clay in a big turntable. By rotating the turntable, the porcelain clay is drawn into a porcelain blank by hand and a blank drawing tool.

Fourthly, the printed porcelain blank is only a prototype, and different molds need to be selected according to the shape to be made to print the porcelain blank into various shapes.

Fifth, the thickness of the blank just printed is uneven. It is necessary to trim and scrape the printed blank neatly and symmetrically through the trimming process.

6. Squeezing water is an essential process, that is, washing off the dust on the blank with clear water to prepare for the next processes such as drawing and glazing.

Seven, painting on the blank is a major feature of ceramic art,

There are many kinds of drawing blanks, some are freehand brushwork, some are sketched with good drawing paper, no matter how to draw blanks, they are the crowning touch of ceramic technology. Eight, the glazed porcelain blank is rough and dull, but it is completely different after glazing, smooth and bright: different glazing processes have completely different effects.

Nine, kiln fire for thousands of years, endless, porcelain blanks carefully carved by dozens of tools, fired at thousands of degrees in the kiln, just like an ugly duckling will become a beautiful swan.

After several days of firing, the porcelain blank in the kiln has turned into exquisite porcelain fragments and can't wait to stand out from the open kiln door. The above is the traditional production, and now the more popular is the "Xuanyi high-temperature porcelain statue", which is in one step.

How to identify the quality of ceramics

First of all, we should know the difference between ceramics. The characteristic of pottery is that the kiln temperature is relatively low, so the clay remains loose structure after sintering.

Its water absorption is high, and the mechanical strength of pottery is not very good, so it is easy to be damaged. In order to improve pottery, make its surface easy to clean and its structure more compact, our ancestors developed the method of glazing. When the glaze is fired in the kiln, it will melt into glass, evenly fill the gaps on the surface of the pottery, and form a dense protective layer. The quality of porcelain depends not only on the tire below, but also on the glaze. When selecting porcelain, we should pay attention to the quality of the glaze itself besides tapping and observing. If the glaze is rough and there are a lot of trachoma, it shows that the glaze quality is not good and there are potential damage hazards. Secondly, we often buy ceramic ware with various colored glazes for beauty, so we need to distinguish different kinds of colored glazes. There are two ways to realize colored glass: over-glaze color and under-glaze color, and the over-glaze color is not suitable for occasions that may be exposed to food because of the heavy metal-rich colored glass. Overglaze color and underglaze color can be determined by carefully observing the color distribution in the glaze layer. As the name implies, overglaze color and underglaze color correspond to two different coloring methods respectively. Although the colored glaze of underglaze color is separated from the outside world by transparent enamel,

However, in the process of glazing and firing, there is still the possibility of heavy metals infiltrating outward. In particular, some manufacturers use excessive lead-containing glaze in the production process in order to make their products bright and clear. What, decorate with your own money? !
