Bisque is a ceramic used in the making of pottery. It is made by heating raw materials, such as clay, to a very high temperature and then cooling quickly. This produces a strong material yet can be easily molded into different shapes. Bisque is often used to make figurines, vases, and other decorative items.
Greenware Vs. Bisque – What Is the Difference?
Ceramic greenware refers to clay pots that have not been fired. They are typically soft and fragile, requiring special care when handling. On the other hand, bisque is a term used to describe what is ceramic bisque in more detail.
Bisque is a type of unglazed ceramic ware. It has a porous surface that readily absorbs glazes and decoration, making it ideal for painting, glazing, and firing. Unlike greenware, bisque does not need to be dried before firing.
Rather, it is placed directly into the kiln, heated to high temperatures (usually between cone 06 and 04). This process hardens the clay and gives it a smooth finish.
How Long Does a Bisque Fire Take?
Ceramic bisque firing can take approximately 10 hours, depending on the size and type of fired piece. Once the bisque is complete, it can be glazed and re-fired to create a finished piece of pottery.
Bisque firing is the first step in the process of creating pottery. The clay body is hardened in a kiln to prepare it for glazing during this stage. The high temperatures used during bisque firing also help remove any moisture from the clay body, preventing pieces from warping or cracking during subsequent firings.
After bisque firing is complete, pieces can be glazed and fired again to create a finished piece of pottery.
How to Paint Ceramic Bisque
Ceramic bisque is unpainted and unglazed ceramic ware. It has a porous surface that absorbs paint readily. Painting bisque is similar to painting any other type of ceramic piece.
However, it requires a few extra steps to prepare the surface for painting because it is not glazed. With a little time and effort, you can transform a plain piece of bisque into a work of art.
Here are the steps on how to paint ceramic bisque:
- Start with clean bisque – Bisque fired in a kiln is ready to paint; however, if you are working with raw clay bisque, you will need to fire it first. Once your bisque is clean and dry, you are ready to start painting.
- Use a primer – Because the surface of the bisque is porous, it is important to use a primer before painting. This will help the paint adhere better and prevent it from chipping or flaking off later.
- Choose the right paint – Not all paints are created equal. Some paints are specifically designed for use on ceramic bisque, while others are not. Be sure to read the labels carefully before making your purchase.
- Apply multiple coats – Once you have applied your primer and chosen your paint, it is time to start painting! Apply multiple thin coats of paint, allowing each coat to dry completely before adding the next one. This will help ensure that your final product is smooth and even.
- Seal the deal – Once you have finished painting, you must seal the bisque to protect your work. You can do this by spraying it with a clear sealant or brushing on a clear glaze layer.
Why Should You Ceramic Bisque Before Glazing?
Ceramic bisque is an important step in the pottery-making process. It allows you to get a feel for the clay and how it will respond to different treatments before adding color or pattern with glazes. Bisque also gives your piece a more finished look and strengthens it to withstand the high temperatures of firing.
There are many reasons why ceramicists choose to bisque their work before glazing. By bisquing, you can avoid problems that might occur if you glaze over raw clay. For example, if you glaze over unbaked clay, your piece may not be strong enough to withstand the high firing temperatures and could crack or break.
In addition, glazes can sometimes react with unbaked clay, causing them to run or pool in unexpected ways. By bisquing first, you can avoid these problems and ensure that your piece turns out exactly as you intended.
Therefore, if you’re new to ceramics or are thinking about trying it for the first time, bisque your work before glazing! It’s an important step to help you create beautiful and long-lasting pieces.

Why Is it Called Bisque Pottery?
The word “bisque” is derived from the French term for a type of soup made from crustaceans. The word eventually came to be used to describe unglazed, fired clay that had been ground into a powder and could be used in pottery making.
Bisque refers to both the clay body mixture and the firing process. A bisque fire is typically done at a lower temperature than stoneware or porcelain, around 1800 degrees Fahrenheit. This produces a strong and chip-resistant product but is still porous enough to absorb glazes well.
How Can You Tell if Something Is Bisque?
If you’re not sure if something is bisque, there are a few things you can look for. First, bisque is usually unglazed or only partially glazed. Second, it is often slightly porous and has a matte finish. Finally, bisque is usually denser and heavier than other types of pottery.
Is Bisqueware Fragile?
Yes, ceramic bisque is fragile and should be handled with care. It is best to store it in a cool, dry place. Avoid drastic temperature changes, as this can cause the bisque to break. Sharp objects can also damage Bisqueware, so take care when handling it.
Ceramic bisque offers many benefits for both professional and amateur ceramicists. It is a versatile product that you can use to create various projects. With its wide range of colors and sizes, it is also easy to find the perfect piece of bisque for your project. Whether you are looking to create a one-of-a-kind piece or mass-produce many pieces, ceramic bisque is an excellent choice.
