What is Pottery?
Pottery refers to the process of creating objects, typically vessels or containers, using clay that is shaped and then fired at high temperatures. The word “pottery” can also refer to the finished products themselves, which are often functional and decorative.
Clay is the primary material used in pottery, and it is sourced from various locations around the world. The clay is first prepared by removing impurities and adding water to make it more malleable. Once the clay has been prepared, it can be shaped into various forms using a variety of techniques, such as hand-building or throwing on a potter’s wheel.
After the clay has been shaped, it is left to dry until it reaches a leather-hard state. At this point, any additional decorative elements can be added, such as carving or applying glazes. Glazes are a type of liquid glass that are applied to the pottery surface and provide both visual appeal and protection.
Once the pottery is completely dry and has been decorated, it is fired in a kiln to high temperatures, typically around 1200 to 1400 degrees Celsius. This firing process transforms the clay into a durable and long-lasting material, making it suitable for everyday use.
Pottery can be categorized into different types based on its intended use and the techniques used to create it. Some examples include earthenware, stoneware, and porcelain. These different types of pottery have distinct characteristics in terms of their appearance, hardness, and the temperatures at which they are fired.
Pottery has a long history and has been created by various cultures around the world for thousands of years. It has served a wide range of purposes, from practical uses such as storage and cooking vessels, to more artistic and decorative forms.
Types of Pottery
There are various types of pottery, each with its own unique characteristics and production methods:
- Earthenware: This type of pottery is made from clay that is fired at relatively low temperatures. It is porous and often glazed to make it waterproof. Earthenware pottery is known for its rustic and traditional appearance.
- Stoneware: Stoneware pottery is fired at a higher temperature than earthenware, resulting in a denser and more durable product. It is usually finished with a glaze that gives it a smooth and glossy surface. Stoneware pottery is commonly used for everyday tableware.
- Porcelain: Porcelain is a type of pottery that is made from a specific type of clay that has a high percentage of kaolin. It is fired at very high temperatures, resulting in a vitrified and translucent product. Porcelain is known for its elegance and delicate appearance.
- Raku: Raku pottery is a Japanese technique that involves removing the pottery from the kiln while it is still hot and placing it in a container filled with combustible materials, such as sawdust or straw. This process creates unique and unpredictable patterns on the pottery’s surface.
- Majolica: Majolica pottery is characterized by its colorful and intricate hand-painted designs. It originated in Italy in the 14th century and is typically made from earthenware. Majolica pottery is often used for decorative purposes.
Each type of pottery has its own appeal and is used for a variety of purposes, ranging from functional to decorative. Whether you prefer the rustic charm of earthenware or the delicate beauty of porcelain, there is a type of pottery to suit every taste and style.
Differences in Clay
One of the main differences between pottery and porcelain lies in the type of clay used to create each material. Pottery is typically made from earthenware clay, which has a lower firing temperature and is more porous. Porcelain, on the other hand, is made from a type of clay called kaolin, which has a higher firing temperature and is non-porous.
Earthenware clay is derived from sedimentary rocks and contains more impurities, such as iron and other minerals, which give pottery its characteristic colors and textures. It is easier to work with and is often used to create handmade pottery and decorative items.
Kaolin clay, on the other hand, is a pure and refined clay that is often referred to as China clay. It is named after the region in China where it was first discovered. Because of its purity and low iron content, kaolin clay can be fired at high temperatures, typically around 1200-1400 degrees Celsius, resulting in a dense and glass-like material that is translucent when thin.
Due to the difference in clay composition, pottery tends to have a more rustic and earthy appearance, while porcelain has a more refined and delicate look. Pottery is also more likely to absorb liquids, while porcelain is resistant to staining and is often used for tableware.

- Final firing: After glazing, the pottery is fired in a kiln at a high temperature. This final firing melts the glaze and transforms the clay into a hardened, durable material.
- Finishing touches: Once the pottery has cooled, any final touches such as sanding, polishing, or adding decorative elements can be done.
- Quality control: Before the pottery is ready for use or sale, it undergoes a quality control process to ensure that it meets the desired standards of craftsmanship and aesthetics.
The process of making pottery is a labor-intensive and time-consuming craft. It requires patience, attention to detail, and a deep understanding of the properties of clay and glazes. From the initial design to the final finishing touches, each step contributes to the unique character and beauty of the finished piece.
Throwing
Throwing is the process of shaping pottery or porcelain on a potter’s wheel. It is a technique that requires skill and practice to master. During throwing, the potter uses their hands to shape the clay into various forms such as bowls, plates, vases, or cups.
The potter’s wheel is a flat surface that spins on an axis. The potter starts by wedging the clay, a process that involves removing air bubbles and ensuring the clay is pliable and even. The wedged clay is then centered on the wheel, with the potter using their hands and fingers to shape it.
Coiling and pinching are other techniques that can be used to shape pottery or porcelain, but throwing on a wheel is often preferred for its efficiency and ability to create symmetrical forms.
Throwing allows for greater control and precision in shaping the clay compared to other techniques. The potter can use various tools, such as sponges or ribs, to refine the shape and texture of the piece. The speed at which the wheel spins can also affect the outcome, with slower speeds allowing for more intricate details and faster speeds enabling the creation of larger forms.
Once the desired shape is achieved, the potter will use a wire or cutting tool to remove the pot from the wheel. The formed piece is then left to dry before it undergoes additional processes such as trimming, glazing, and firing.
Throwing is a fundamental skill in the creation of both pottery and porcelain. Mastering the art of throwing requires a combination of technique, creativity, and experience.
What is Porcelain?
