Six. Color mud inlaid: Filling mud is an important process program for realizing the graphics and color gradients of building water. After the painters and painters are decorated, after the knife is engraved, they are filled in the carved groove with fine colored mud. The dry and wet of the mud should be grasped well. It is not easy to fill in it too dry, and it will even break the billet. It is too thin and it will be filled with false. It will fall off during the firing process. In terms of color, we must also work hard to restore the original painting, so we must communicate with the author before filling the mud.

Seven, removing mud to take care

The main steps are: 搟, pressure, scraping. When the color mud is dry to a certain degree, we have to make mud, that is, the excess mud is carved into the groove area to the picture, such as the mud is not enough to replenish the mud; Color mud bubbles.

11, firing

The firing temperature is generally about: about 20%to 1200 degrees, the contraction rate is about 20%, the firing time is 10 to 10 to from 10 to to 12 hours. It is divided into oxidation fever and reduction burning method. The oxidation fever is to maintain sufficient oxygen supply in the kiln during the firing process. The restore burning is rising to about 900 degrees at the kiln temperature to reduce the oxygen supply in the kiln. The white mud of oxidation is yellow and white, commonly known as u0026 ldquo; ivory white u0026 rdquo;, red mud is pork liver color. The color of the oxidized fur changes less color after polishing; the restore white mud is blue and gray, and the red mud is dark brown. After polishing the color changes greatly, you can get pure black, bronze, and cyan -gray.

The purple pottery of the newly released kiln is covered with a layer of metal texture. Its coat is removed. It shows its original appearance. This process is to talk about the characteristics of our purple pottery: glazed polishing. There is a glaze but glaze -like brightness. This is a very special process. Traditional materials are fine sand or pebbles on the side of the water. They can all polish the effects of smoothing like mirrors on the surface of the purple pottery. This is for light. Yuguang we generally use the sandblast to remove the fire skin, and then polish it artificially on the wheels.
