What is the manufacturing process of blue and white porcelain? Thank you.

Every piece of blue-and-white porcelain has gone through dozens of processes and dozens of technical key points from kneading mud to firing, all of which come from a series of skills accumulated by artists over the years and have been carefully drawn. Even similar content has its own unique life.

Manufacturing technology of blue and white porcelain;

One: Mud kneading, the purpose is to empty the air bubbles in the mud, so as to further compact the mud. If this process is omitted, the green body is easy to appear bubbles, and if the green body is too dry, it is easy to be broken and deformed during firing.

Two: blank making, the traditional circular machine blank, that is, roughly corresponding blanks are made according to the final machine type for later production of printing blanks.

Three: printed blanks, blanks, naturally dry in the shade after a certain period of time (they must be naturally dried in the shade under certain humidity and temperature conditions, and cannot be exposed to the sun. The blank formed by the blank must be placed obliquely on the blank plate, not vertically. The purpose of printing blank is to make the hand-shaped circular device uniform after firing.

Fourthly, blank making is to trim the printed blank to make it smoother and rounder.

Five: when the glaze, generally made of timely, feldspar, clay. The methods of glazing ceramics are spraying, blowing, dipping, pouring and swinging. The inner glaze (inner glaze) and bottom glaze (foot glaze) adopt the traditional glaze throwing method, and the outer glaze adopts the glaze dipping method.

And 6, drawing the blank, swinging the inner glaze blank, and entering the blank drawing process.

Seven: external glazing, the finished porcelain blank needs secondary glazing.

Eight: write the bottom payment and apply the bottom glaze.

Nine: firing, according to the structural size of the kiln body and the size of all the green bodies to be fired, a reasonable fire path should be left, otherwise the firing will fail.

Ten: open the kiln. After 12- 18 hours of natural cooling, the kiln can be opened when the temperature in the kiln body drops to normal temperature.

XI: finished product
