One of the main uses of kaolin clay that help potters the most is in ceramic, proclaim and chinaware. Pottery is made by combining natural raw materials, such as clay, earth minerals, and water, and molding them into shapes. Once the clay body is formed, it is fired in a high temperature oven until it becomes hard and heat resistant. There are a number of ceramic techniques that are used to make both functional and decorative ceramic pieces. Potters use the spinning wheel to create symmetrical pottery and the slippery cast to create multiples of a single object. They can also use manual construction techniques such as rolling, twisting, and pinching sheets. Local potters in the Near East admired the elegance and durability of porcelain and faience stone and sought to recreate their precious qualities. Porcelain requires white kaolin clay that is fired at an extremely high temperature; Neither the clay material nor the amount of wood required for continuous firing at high temperatures was available in the Near East. Iraqi potters have devised ways to mimic the smooth white surface of Chinese pottery. Using locally available clay, they covered the pottery body with an opaque white layer called an engobe and decorated it with designs in cobalt blue and other colors in imitation of Chinese porcelain. Kaolin clay is one of the widely available raw materials for making ceramic pieces. Different types of clay and combinations of clay with different variations of silica and other minerals produce different types of pottery. 
When working with clay, it is important to protect yourself from inhaling dry clay dust. This dust contains silica, which can remain in the air for hours and damage the lungs. To protect yourself, wear a mask, understand what ingredients are in the clay you are using, and use wet, pre-mixed clay objects. Kaolin clay differs from inelastic clay and fine sand in its ability, when moistened with an adequate amount of water, to form a cohesive mass and retain its shape when formed. This quality is known as the color of clay. When heated to high temperatures, clay also partially melts, resulting in a hard, rock-like solid known as ceramic. Because of its mineral purity, kaolin clay is used for porcelain. Although kaolin clay has a certain range of colors, they are all very light in color. When wet, it will be a light gray in color and will pick up in a range of very light gray or beige to almost white and white. Kaolin clay is not as plastic as other clays and is difficult to work with. Pure kaolin clay is fired to maturity at about 3,272 Fahrenheit (1800 C). It is often mixed with other clays to increase workability and reduce the burning temperature. Many porcelain bodies are a mixture of kaolin and spherical clay. 
kaolin clay uses
Kaolin clay is a mineral with various uses and applications in different industries such as medicine, ceramics, paper and chinaware. High quality kaolin is a good raw material that imparts flexibility and strength during the manufacturing process of porcelain or ceramic. It can be used as a filler or as the main body for white ceramic production fixtures. The white color is mainly made up of the natural property of kaolin. Kaolin is the common name for the mineral kaolinite, which is a lime aluminum silicate mineral formed by the weathering of a hard aluminum silicate such as feldspar. It is also known as Chinese clay and is the main source for most modern porcelain. It can be white or tinged with pink or red hues depending on the impurities present. Named after a city in China near which the mineral is found, it is a very common mineral that is mined in many regions of the world. This versatile mineral is found in many industries and some uses of kaolin, as well as clays for pottery and pottery, are in the papermaking, paint industry, and cosmetics. 
Historically, one of the main uses of kaolin was the manufacture of ceramics, which is still the main component of most ceramic products, including porcelain and stone. Pure white kaolin is particularly preferred for these products due to its color, although naturally colored kaolin is also used. Another use of kaolin is the manufacture of special ceramic products called refractories, which are used to make kilns and kilns and furnace linings in foundries. In the modern era, papermaking has become one of the biggest uses of kaolin. Kaolin is infused into paper products to improve their white color, opacity, and ability to retain ink. It also improves print quality and facilitates paper finishing. Many glossy papers contain a large amount of kaolin, which can be infused into the paper using special adhesives. Many types of paper can contain up to 70% kaolin by weight, and the paper industry uses most of the kaolin produced worldwide. 
kaolin clay uses in ceramic
Kaolin clay with its several uses is mainly used in ceramic industry. Kaolin is also known as porcelain clay or china clay and is used to produce porcelain, with non-ceramic applications including papermaking and plastic production. This is mainly due to its mineral purity. It is the purest type of clay known to man. It is a natural clay called basic clay because it is found near its source. Although this type of clay has some types of color, it is often light in color. It's just a little plastic compared to other types of clay, which makes it difficult to work with. Therefore, it is usually mixed with plastic clay to help improve its workability. There are two main colors of kaolin, white kaolin and red kaolin. The former is more common and widely used as detailed below. Red kaolin is very similar except that it has a red color due to oxidation of the iron oxide. Apart from its low workability, it also has a low level of plasticity. The poor plasticity of kaolin is mainly due to the relatively large particle sizes. Therefore, precast kaolin ceramics can easily break when bent, if they are in a wet, unfilled state (ie, suboptimal moisture levels). Among all clay classes, kaolin has the highest temperature aging levels (high fire clay) with temperatures reaching 1800°C. In most cases, it is mixed with other clays to increase workability and reduce combustion temperature. When burned, porcelain can become very hard and transparent. Also, its cast surface becomes so smooth and shiny that no glazing is needed. 
One drawback to fine-sawing porcelain is that it is very brittle and prone to cracking at the edges, another reason to mix kaolin with other clays to make more durable items. In contrast, kaolin is resistant to corrosion in its processed form. Most porcelain items are made from a perfect blend of kaolin and spherical clay. Kaolin is widely used in the production of glossy paper. It is also commonly used in the production of morphine. For the production of kaolin-containing ceramics and bricks, reports have shown that bentonite can be added in proportions of about 2% and has been shown to increase the strength and density of the bricks produced without increasing cost. Bentonite itself is a form of clay. One of the most widespread industrial uses of kaolin is the manufacture of ceramics, earthenware and wall and floor tiles. Due to its ideal properties for pottery making, some people call china clay kaolin for its role in the production of whiteware. Kaolin clay has a high melting temperature and its naturally bright white color makes it useful for making pure white pottery, porcelain, sanitary wares, and kaolin pottery. Since kaolin contains low concentrations of iron or alkali, it is ideal for use in various forms of ceramics. When producing pottery and whiteware, manufacturers often combine kaolin with additional silica and feldspar, along with a small amount of another type of clay called spherical clay, which is a light-burning plastic clay. The combination of kaolin and other components allows ceramic manufacturers to achieve optimum plasticity, shrinkage, glazing, and other processes to properly form and heat tools. Kaolin provides a high resistance to drying, which means that, as an additive, it helps to harden and strengthen the final product, which is essential in the manufacture of ceramic articles. 
kaolin clay uses that help potters
Kaolin clay as an important mineral has various uses that can help potters in ceramic industry. Kaolin or kaolin is a primary clay (residue) produced by the weathering of felsic rocks by internal forces that do not move from their layer of origin. Since the sediment does not move, it is purer than the secondary clay under the liner. The composition of this mineral is greatly influenced by hydroelectric energy and hot steam from the Earth's core. Since water currents do not affect the ore in any way, high-quality kaolin is not mixed with any organic matter, such as chickpeas or rotted leaves. As a result, the clay will have a whiter color than any other sediment. In addition to kaolin, the minerals found in the top layer of soil are also called "basic clays". Some of these minerals are bentonite, feldspar, quartz, and dolomite. When dry, the texture of the base clay is very brittle. This is because the size of the formed particles is not symmetrical or angular, unlike secondary clay particles, which are embedded in parallel plates. Also, quartz and alumina cannot be found in the same layer as other primary minerals. However, both are classified as primary types of clays because they are a by-product of kaolin clay formed from the weathering of felsic rocks. Porcelain containing kaolin is heated, shaped, and dried at a temperature of 1000°C or more. Depending on the additional ingredient being put into the mix, manufacturers can produce different types of ceramic using this method. In addition, kaolin has many unique properties compared to other materials. More fragile in its raw form. However, kaolin adds strength and durability to pottery once it has been treated and modified.Less elastic compared to other sedimentary clays. In other words, it is difficult to configure without additional components. Its low iron content causes a prominent white colour.High quality kaolin has the same properties as standard kaolin that you can find on the market today. However, metals with better purity levels are claimed to be more effective in reducing shrinkage and adding strength to ceramic compounds. Therefore, this clay cannot be used alone but must be mixed and matched with other materials. 
- Kaolin mixed with other materials
Many other materials can be combined with kaolin in the commercial-scale ceramic production process to achieve the best result. These materials are:
- Ball clay : This material is a type of raw ceramic that does not fall under any category of ceramic or earthenware that absorbs water. Porcelain stoneware is classified as a sedimentary clay, and several types of stoneware contain enough feldspar, which is vital for commercial pottery production. Stoneware clay is very flexible and easy to dry. This material is widely used with acid and alkali resistant materials in tiles, art ceramics and pipes. In Indonesia, this clay is widely available in West Java.
- earthenware: Porcelain clay is an ordinary clay used in the production of building bricks, lined pottery, and other types of pottery. It contains a high percentage of iron oxide. Some tiles have a flexible texture, while others are a bit brittle due to their high sand content.
This clay appears yellow, orange, red, brown, or black during the burning process. The color depends on the high combustion temperature and the amount of iron oxide inside the ore. It is normal for terracotta clay to have a red-brown, green or gray color.
- Silica: This material is necessary to reduce cracks during the drying process. It also reduces the burning time and improves the overall product quality. Moreover, silica has the most prominent role as a basic material in the combustion process, as it can excellently retain the heat needed to change the chemical compound. Another form of silica used in the production of pottery is flint. This mineral has a smooth texture and a high level of purity. Flint is usually added during the glazing process to reduce cracking.
- Feldspar, lime and magnesite: When the raw materials are burned to produce ceramics, the field melts and forms a glass that makes particles of clay and other materials stick together. Meanwhile, lime and magnesite are mainly composed of calcium and magnesite metal carbonate form
