When it comes to working with clay, there are different types that serve different purposes. Two common types of clay that you may come across are potters clay and ceramic clay. While they may seem similar, there are some key differences between the two. If you're a beginner, you might want to check out this guide to choosing the right modeling clay for your project.
Potters clay, also known as pottery clay or earthenware clay, is a versatile type of clay that is commonly used by potters and ceramic artists. It is a natural clay that can be found in various parts of the world and is known for its plasticity, which means it can be easily shaped and molded.
Potters clay is typically used for handbuilding techniques, such as pinch pots, coil pots, and slab construction. It can also be used on a pottery wheel for throwing, which is the process of shaping clay on a spinning wheel.

One of the key characteristics of potters clay is its lower firing temperature. It is usually fired at temperatures between 1,800 to 2,300 degrees Fahrenheit (982 to 1,260 degrees Celsius). This lower firing temperature allows the clay to retain its porous nature, making it suitable for functional pottery pieces like mugs, bowls, and plates.
Ceramic clay, on the other hand, is a type of clay that has been processed and refined to remove impurities. It is often referred to as stoneware clay or porcelain clay. Ceramic clay is known for its strength, durability, and ability to hold intricate details.
Unlike potters clay, ceramic clay is typically used for creating non-porous and vitrified ceramics. Vitrification is the process of transforming clay into a glass-like state through high-temperature firing. This makes the ceramics waterproof and more resistant to wear and tear.
Ceramic clay is commonly used for wheel-thrown pottery, as it allows for precise shaping and delicate forms. It is also popular for creating sculptures and decorative pieces that require intricate details.

The firing temperature for ceramic clay is higher than potters clay, usually ranging from 2,200 to 2,400 degrees Fahrenheit (1,204 to 1,316 degrees Celsius). This high firing temperature ensures that the clay reaches its maximum strength and durability.
In summary, the main differences between potters clay and ceramic clay are:
- Potters clay is more plastic and easier to shape, while ceramic clay is stronger and holds intricate details.
- Potters clay is fired at lower temperatures, while ceramic clay is fired at higher temperatures for vitrification.
- Potters clay is commonly used for functional pottery, while ceramic clay is used for non-porous ceramics and decorative pieces.
Both types of clay have their own unique qualities and uses in the world of clay crafts.
