How Was Porcelain Invented?

No comments

Porcelain was invented in China during the Tang Dynasty (618-907 AD) and is a type of ceramic material that is fired at a high temperature to create a hard, translucent, and glass-like surface. It is known for its durability, resistance to water, and its ability to be molded into intricate and delicate shapes.

The invention of porcelain is attributed to the Chinese craftsman Jingdezhen, who discovered that combining feldspar, kaolin, and quartz materials in specific proportions produced a highly prized hard and translucent ceramic material. This mixture was then shaped and fired at incredibly high temperatures, resulting in a dense, glass-like surface.

The delicate and intricate designs found on porcelain objects were achieved through a technique called underglaze decoration, which involves painting designs onto the unglazed porcelain with a fine brush. Once these designs were completed, the porcelain was coated with a clear glaze and fired again at high temperatures, fusing the layers of color and design into the final product.

Porcelain quickly became a prized material, not only in China but also among European merchants who introduced it to the Western world. Today, porcelain continues to be produced and admired as a symbol of refinement and elegance in art and design.

The Invention of Porcelain: A Fascinating History

The Early Origins of Porcelain

If you love fine porcelain, you might be fascinated to learn that it all began during the Tang Dynasty in China. However, the earliest ceramics that closely resemble porcelain were first made in Shang China around 1600 BCE. Back then, the original term used to describe the ceramic material was “high-fired,” as firing temperatures of over 1,300 degrees Celsius were needed to create it. Unlike today, the original porcelain was created by mixing a type of clay called kaolin with feldspar and quartz.

Over time, the Chinese learned to create even more elegant porcelain using a type of clay found in Jingdezhen in the Jiangxi province of China. By the time of the Ming Dynasty, porcelain was highly prized in China, a symbol of wealth and prestige. The porcelain produced during this period was of particularly high quality due to the use of a new type of glaze which added translucency to the pieces. In addition, a technique called “underglaze blue” was developed, which allowed artists to create intricate designs on the porcelain, making each piece an exquisite work of art.

The Rise of Porcelain in Europe

Porcelain arrived in Europe in the 16th century, thanks to trade with the East. European potters were fascinated by the material but struggled to understand and recreate it. Europeans tried for many years to produce porcelain like the Chinese gems but were not quite successful. The Chinese had been able to make porcelain with outstanding quality for centuries, and for a long time, Europeans failed to capture the same level of beauty.

The intrigue of European craftsmen was persistent, and it wasn’t until the early 18th century that the secret of hard-paste porcelain was finally discovered by a German alchemist named Johann Friedrich Bottger. Hard-paste porcelain is made by combining kaolin, feldspar, and quartz in specific proportions and then baking the composite at high temperatures to melt and homogenize it. This new type of porcelain was called “white gold” and differed from the Chinese because it was more mechanically robust. The true ceramic revolution had begun, and great factories were established in Germany, France, England, and many other European countries.

Over time, European porcelain makers became more innovative and produced more delicate and elegant porcelain pieces. They adapted the Chinese techniques and added their own variations, mixed clay with bone ashes and other ingredients, used enameling and painting techniques, and created outstanding designs. The English porcelain makers, for example, focused on creating an elegant and refined design, while the French used porcelain as a canvas for their ornate decorative designs, including floral motifs and garlands. The charm and beauty of this fine ceramic material continued to spread, and today, porcelain remains a precious gem that great designers and collectors treasure.

The Ingredients of Porcelain

Porcelain is a beautiful and sophisticated type of ceramic that originated in Ancient China. It is made from a special blend of clay that is combined with other minerals to achieve its unique properties. In this section, we will take a closer look at the three primary ingredients of porcelain and explore how they are sourced, processed, and integrated into this beautiful and valuable material.


Kaolin, also known as China clay, is one of the most vital ingredients of porcelain. It’s a type of clay that is highly valued for its purity, whiteness, and plasticity. This clay is sourced from various locations worldwide, such as China, England, and the United States.

China has been the primary exporter of kaolin for centuries, and the clay there is of exceptional quality. The extraction process involves large-scale open-pit mining, where kaolin is strip-mined, crushed, and transported to processing plants. The clay is then purified and refined through a series of stages that involve sieving, blending, and drying to remove impurities and achieve the desired characteristics.

In the United States, kaolin is mainly found in Georgia and South Carolina, and the extraction process involves a more environmentally-friendly approach. The clay is removed from the ground using surface mining techniques that minimize soil disruption and preserve natural habitats. Additionally, kaolin mining in the United States is strictly regulated to ensure sustainable practices that protect the environment.


Feldspar is another critical ingredient in porcelain, used to lower the melting point of the clay and increase its durability. It’s a group of minerals that include orthoclase, microcline, and plagioclase that are rich in silica, alumina, and potassium. Feldspar deposits are widespread, with significant sources found in Norway, Italy, and the United States.

The extraction process for feldspar varies depending on the deposit’s location, type, and depth. For example, in Norway, feldspar is mined underground, and the process involves blasting and drilling tunnels that follow the veins of feldspar. In Italy and the United States, feldspar is extracted through open-pit mining, where the mineral is broken up using explosives and transported to processing plants.

Once the feldspar is extracted, it’s crushed, ground, and sieved to remove impurities and prepare it for use in porcelain. The refined feldspar is then mixed with kaolin and other minerals to create a blend that’s ready for firing in kilns at high temperatures.


The third essential ingredient in porcelain is quartz, a mineral known for its hardness, durability, and resistance to heat and pressure. Quartz is abundant worldwide, with major sources found in Brazil, the United States, and Madagascar.

The extraction process for quartz involves open-pit mining, drilling, or blasting the mineral from the earth’s crust and transporting it to processing plants where it’s crushed, ground, and refined. The refined quartz is then combined with kaolin and feldspar to create a fine, ceramic mixture that’s ready for modeling and shaping.

To sum up, porcelain is made from three primary materials: kaolin, feldspar, and quartz. These minerals are sourced from different parts of the world and processed to achieve optimal purity and quality. The resulting blend is then molded, fired in kilns at high temperatures, and glazed to create the exquisite porcelain objects that we admire and collect today.

The Manufacturing Processes of Porcelain

Clay Preparation

Porcelain is an exquisite material that is made from a mixture of clay, feldspar, and quartz. The clay used in the manufacturing process is typically a specific type of white clay called kaolin. To prepare the clay, it is mixed with water and then strained to remove any impurities that might weaken the finished product. Afterward, the clay is left out to dry in the sun, which allows the excess water to evaporate before it is used. This ensures that the clay will be of the correct consistency when it is used to make porcelain.

Shaping the Clay

Once the clay has been properly prepared, it is time to shape it. This can be accomplished by hand or with the help of a potter’s wheel. The idea is to mold the clay into the desired shape and size. This is a crucial step in the manufacturing process since the final product’s shape and size are critical to its functionality and beauty. After shaping, the clay is left to dry completely. This can take up to several days, depending on the size of the clay piece.

Firing the Porcelain

The final and most important step in the manufacturing process is firing the porcelain in a kiln. This is done at an extremely high temperature, typically between 1,200 and 1,400 degrees Celsius. The high temperature causes the individual elements in the clay mixture to melt and combine, creating a dense, glass-like substance. The firing process can take up to several days, depending on the size and thickness of the porcelain object being created. During this time, the temperature of the kiln is carefully monitored to ensure that the porcelain is heated evenly and thoroughly.

Once the firing process is complete, the kiln is left to cool down slowly. This is critical to the final product’s strength and durability since rapid cooling can cause the porcelain to crack or shatter. After the kiln has cooled completely, the porcelain is removed and examined. If it has been fired correctly, it will be hard, dense, and sturdy. It can be left as it is or painted, glazed, or otherwise decorated depending on the purpose of the porcelain piece.
