First, the production process of ceramic spoon
1. Manufacturing technology of ceramic spoon: practice mud, and step on the mud with your hands or feet until the air in the mud is squeezed out and the water in the mud is even.
2. Blank: After the mud is changed into the shape of a bird's nest, it is strongly placed in the center of the turntable, so it is firmly stuck on the turntable. Dump the mud in the center of the rotary table, unfold it by bending, and draw a blank general appearance.
3. Ink blank: the seal shape is made by rotating the arc of the blank shape. Cover the semi-dry blank on the mold, evenly press the outer wall of the blank, and then demould.
4. Drying the blank: processing the blank, forming it on a wooden frame, and drying.
5. Carving: Draw patterns on the dry body with bamboo, bones or iron knives.
6. Glazing: Put the glaze on the rotatable brake through the wheel glaze. Centrifugal glazing is used to spread the glaze evenly, so that the product is coated with thick and uniform glaze, and the excess glaze is coated on the outer panel.
7. Combustion kiln: Ceramic products are put into enamel, which is the container for firing ceramic products. Made of refractory material, it can prevent direct contact between porcelain kiln and kiln fire and avoid pollution, especially suitable for white porcelain incineration. The fuel is pine, so as to complete technical guidance, fire measurement and control the temperature change of the kiln.
Second, ceramic tableware purchase skills
1. When choosing regular businesses and markets, it is best not to buy in informal places, such as roadside or small vendors. Approved the production of ceramic tableware, because there are national regulations that ceramic tableware should be dissolved with 4% acetic acid solution before leaving the factory, and the lead content of tableware should be less than 7 mg/L, and the cadmium dissolution amount should be less than 0.5 mg/L, so it is suitable for use. Ordinary manufacturers usually meet this requirement, and informal manufacturers cannot guarantee to meet this standard.
2. Pay attention to the color of the ceramic spoon, the glaze is even, the pattern looks beautiful and not rough, and the surface of the tableware is smooth when touched by hand, especially the inner wall. High-quality tableware cannot have small uneven particles.
3. Smell ceramic tableware, which is high in harmful elements, so don't buy it.
4. don't buy ceramic tableware with bright colors and patterns because of the pursuit of beauty and novelty. In order to look better, some heavy metal additives are usually added to the glaze. Heavy metals are harmful to human body. Therefore, the brighter the ceramic tableware, the more heavy metals it contains, and the easier it is to exceed the standard.
5. It is best to choose glazed and underglaze ceramic tableware. These two processes have higher requirements in the production process, and the content of heavy metals in the pigment is less.
6. Before using ceramic tableware, put it in boiling water for about 5 minutes, or put it in vinegar for 2-3 minutes to dissolve the toxic elements in the tableware.
That's the introduction of the ceramic spoon we brought to you.
