Problems solved by technology

The disadvantages of pottery’s practicality are determined by the traditional raw materials and production process. The raw materials used in traditional pottery are laterite and clay, which are mostly fired at 700-800°C. The plasticity of laterite and clay is poor. If the temperature is too high, it will easily deform. Cracking, and the lower firing temperature will cause the carcass to be basically sintered, but the porosity and water absorption are higher, the water permeability is high, the heat resistance is poor, and the practicability is reduced
[0004] Although the practicability of pottery is not as good as that of porcelain, pottery has a natural, simple, rough and primitive effect, which can cater to modern people's aesthetic psychology of returning to simplicity. Therefore, the improvement of pottery has always been a common concern in the industry. For example, the application number is 201510857692.6 Disclosed is a method for manufacturing decorative art pottery. The decorative artistic pottery uses ordinary clay and river sand as raw materials, and is decorated on the outside of the pottery through underglaze color technology, and is protected by a waterproof adhesive layer. The performance of pottery has been improved, but the function has not been improved

specific Embodiment 1

[0024] Antique pottery handicrafts made of magnetite tailings, including pottery body and painted glaze, the weight of pottery body is as follows: 48 parts of magnetite tailings, 36 parts of laterite, 7 parts of spodumene, volcanic stone 9 copies;

[0025] Among them, the magnetite tailings slag is selected from the magnetite tailings slag in the Yangshan mining area of ​​Dehua, and its chemical composition is: Al 2 o 3 5.19%, Fe 2 o 3 12.6%, SiO 2 49.6%, K 2 O 0.8%, Na 2 O 0.5%, CaO 22.7%, MgO 3.4%, I.L 4.3%;

[0026] Among them, the red soil is selected from Longque Village, Sanban, Dehua County, and its chemical composition is: SiO 2 56.8%, Al 2 o 3 22.6%, Fe 2 o 3 6.5%, K 2 O 3.4%, Na 2 O 0.3%, MgO 0.8%, CaO 0.5%, TiO 2 0.9%, I.L8.2%.

[0027] The parts by weight of the painted glaze are as follows: 24 parts of Dehua low-temperature stone, 13 parts of Dehua limestone, 23 parts of borax, 9 parts of boric acid, 11 parts of quartz, 15 parts of kaolin, and ...

specific Embodiment 2

[0035] The manufacturing process of the antique pottery handicraft made by using magnetite tailings is characterized in that, the above-mentioned antique pottery handicrafts made by utilizing magnetite tailings are prepared, and the specific steps are as follows:

[0036] Step 1, weighing according to the raw material components of the pottery body, performing wet ball milling for 18-20 hours to obtain mud;

[0037] Step 2, making the mud prepared in step 1 into the required pottery green body by grouting or pressing;

[0038] Step 3: The pottery body is first biscuit-fired to form a biscuit at a temperature of 850-900°C, and painted on the biscuit with a painted glaze. The painted glaze is weighed according to the raw material components, and the German Low-temperature stone, Dehua limestone, borax and boric acid are made into frit at 1150-1200°C. When painting, the frit is quenched and then added with quartz, kaolin and color materials, and ball milled for 45-50 hours;

Abstract

The invention belongs to the field of daily ceramic products, and particularly speaking, relates to archaistic ceramic art ware made by utilizing magnetite tailing and a manufacturing process thereof. According to the archaistic ceramic art ware made by utilizing the magnetite tailing, the magnetite tailing, laterite, spodumene and vesuvianite are used as raw materials for a green body. According to the archaistic ceramic art ware made by utilizing the magnetite tailing, the plasticity of a ceramic green body is improved; the production cost is decreased; the rate of finished products is improved; a ceramic product with the water absorption of 8 percent can be made. A product of the archaistic ceramic art ware is maroon; black granular spots are distributed in a ceramic body, so taht a sand inclusion texture is formed; the archaistic ceramic art ware is good in heat resistance and air permeability, is difficultly ruptured and is improved in practicability; The archaistic ceramic art ware utilizes the waste magnetite tailing, is low in the costs of the raw materials, is energy-saving and environment-friendly, and is suitable to make a flowerpot, a water pot, a retro ornament and the like; an archaistic ceramic made by utilizing the magnetite tailing can be subjected to underglaze colored drawing decoration through a colored drawing glaze; the product is exquisite.

Description

technical field [0001] The invention belongs to the field of daily-use ceramic products, and in particular relates to an antique pottery handicraft and a manufacturing process made of magnetite tailings. Background technique [0002] Pottery crafts are the oldest arts and crafts in China. As far back as the Neolithic Age, there were rough and solid gray pottery, red pottery, white pottery, painted pottery and black pottery. Ancient pottery is a utensil made by kneading clay or pottery clay and then firing it. [0003] In our country, with the gradual maturity of porcelain firing technology, pottery is gradually replaced by porcelain because its practicality and aesthetics are not as good as porcelain. The disadvantages of pottery’s practicality are determined by the traditional raw materials and production process. The raw materials used in traditional pottery are laterite and clay, which are mostly fired at 700-800°C. The plasticity of laterite and clay is poor. If the te...
