Process flow of ceramic water cup

1. Clay training: Porcelain stone is taken from the mining area, pounded with water, washed to remove impurities, and then precipitated into brick-shaped mud blocks. Then mix the mud with water, 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. Pulling the blank: Throw the mud ball on the center of the turntable of the reel car, and pull out the rough shape of the blank with the flexion and extension of the technique.

3. Impression blank: The shape of the impression mold is rotated according to the inner arc of 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. Sharpening the blank: Put the blank on the sharp barrel of the reel car, turn the turntable, and turn it with a knife to make the blank with proper thickness and smooth inside and outside. This is a process with high technical requirements.

5. Drying 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-dry body.

7. Glazing: The ordinary round mouth adopts dipping glaze (immerse the blank in the glaze pot, and lift it up immediately when the edge of the mouth is flush with the glaze surface) or glaze (inject 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 paste), cut utensils (relative to “round utensils”, “round utensils” refer to round utensils formed by the method of drawing blanks, such as bowls, plates, dishes, etc. And the utensils with more complicated forming process, Such as bottles, statues, pots, jars, etc., they are called “cutters”) or large-scale round utensils with blowing glaze (the method is to cover the bamboo tube with spun yarn, dip it in the glaze and blow it with the mouth, and repeat this many times, the thickness of the blank surface can be obtained. uniform glaze layer).

8. Kiln firing: The time process is about one day and night, and the temperature is around 1300 °C. First build the kiln door, ignite the kiln, the fuel is pine wood, guide the piling technology, measure the fire, master the kiln temperature change, and decide the ceasefire time.

9. Color glaze: The color on the glaze, such as multicolored, pastel, etc., is to describe the pattern and color on the glazed surface of the fired porcelain, and then enter the red furnace to bake at a low temperature at a temperature of about 700–800. In addition, before firing the kiln, painting on the green body, such as blue and white, underglaze red, etc., is called underglaze red, which is characterized by the fact that the color is under high temperature glaze and will never fade.
