Xin xiang Ceramic Mug Manufacturer, The following is the production process of the ceramic mug, I hope it can help you.
1. Practicing mud: Porcelain stone is taken from the mining area, pounded with water, elutriated to remove impurities, and precipitated into brick-like mud. Then mix the mud with water to remove the slag, rub it with your hands or step on it with your feet to squeeze out the air in the mud and make the water in the mud even.
2. Drawing the billet: Throw the mud ball at the center of the turntable of the potter's wheel, and draw the rough shape of the billet by flexing and stretching.
3. The impression of the blank: the shape of the impression is to be rotated according to the arc inside the blank, and the semi-dry blank is placed on the mold, and the outer wall of the blank is evenly pressed, and then demolded.
4. Rigid billet: Lay the billet on the sharp bucket of the potter wheel, rotate the turntable, and use a knife to turn the billet to make the billet thickness appropriate and the surface and the inside smooth. This is a process of promotional ceramic mugs with high technical requirements.
5. Expose the billet: Place the processed billet on a wooden rack to dry.
6. Carving: Use bamboo, bone or iron knives to carve patterns on the dried or semi-dried body.
7. Glazing: Ordinary round mouth adopts dipping glaze (dip the blank into the glaze basin, and raise it immediately when the mouth is flush with the glazed surface) or glaze (pour the glaze slurry into the blank and shake it to make the top, bottom, left, and right glaze evenly, and then quickly Pour out the excess glaze slurry), cut ware (compared to "round ware", "round ware" refers to round utensils that are formed by the drawing method, such as bowls, plates, dishes, etc. The molding process is more complicated. Such as bottles, statues, pots, pots, etc., are called "cutting tools") or large round wares with blowing glaze (the method is to cover the bamboo tube with fine yarn, dipped in the glaze and spray with the mouth. Repeat this many times, the blank surface can get the thickness Uniform glaze layer).
8. Kiln: The time course is about one day and night, and the temperature is about 1300℃. Build the door of the kiln first, ignite the kiln. The fuel is pine firewood, guide the piling technique, measure the fire time, grasp the temperature change of the kiln, and decide the ceasefire time.
9. Color glaze: On-glaze colors such as multicolored and famille rose are used to draw patterns and fill colors on the glazed surface of the fired porcelain, and then burn it in a red furnace at a low temperature, at a temperature of about 700℃-800℃. In addition, before firing the kiln, paint on the green body, such as blue and white, red in glaze, etc., it is called red in glaze, which is characterized by color that will never fade under high temperature glaze.
Firing method of custom ceramic coffee mug
1. One-time firing method. That is, after the dried green body is glazed (there are also unglazed), it is put into the kiln and fired (also called the hon-yaki), such as the fine porcelain blue and white porcelain of Jingdezhen, the color glaze (lang red, sacrificial red) , Ujin and other colored glaze porcelain), blue and white Linglong, etc. are all fired at one time.
2. Two firing method. There are low-fire and high-fire biscuit. The former is to use low temperature to burn the dried green body, then hang the glaze, and then enter the kiln to burn at high temperature. There is also a kind of biscuit to increase the water absorption and strength of the body so that it is easy to hang the glaze without being damaged (such as some thin porcelain tires). Only the green body is burned to about 700-960°C, also called biscuit. After being glazed, the unfired slab is put into the kiln and fired according to the one-time firing method. Hard and fine daily-use white porcelain in countries all over the world uses this method. The latter is to first burn the blank at high temperature (1260-1280°C), and then perform low-temperature glaze firing (950-1050°C), such as daily fine pottery and bone ash porcelain. |
