Operation flow and function of ceramic eyelet technology

The production process of ceramic eyelets:

A. Clay training: Porcelain stone is taken from the mining area, pounded with water, washed to remove impurities, and 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.

B. Pulling the blank: Throw the mud ball on the center of the turntable of the reel car, and draw the rough shape of the blank with the flexion and extension of the technique.

C. Impression blank: The shape of the impression mold is to be spun according to the inner arc of the blank. The semi-dry blank is placed on the mold, and the outer wall of the blank is evenly pressed, and then demolded.

D. 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.

E. Drying the billet: Place the processed billet on a wooden rack to dry.

F. Carving: Use bamboo, bone or iron knives to carve patterns on the dried or semi-dry body.

The role of ceramic eyes:

Ordinary round mouth adopts dipping glaze (immerse the blank in the glaze basin, and lift it 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 so that the top, bottom, left and right are evenly glazed, and then quickly dump 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 molding process, such as bottles, , pots, jars, etc., 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 surface of the blank can get a uniform thickness of glaze layer ). Kiln firing: The time course 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. On-glaze colors, such as multicolored, pastel, etc., are painted on the glazed surface of fired porcelain, filled with colors, and then fired in a red furnace at a low 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.
