As a pottery-making beginner, you might have heard about underglaze. It is a type of clay coating that is applied to pottery to make it more colorful and durable. Underglaze can be used on greenware and bisque ware, offering an almost endless array of design choices.
However, if you have never used underglaze before, it can be overwhelming to know where to start. In this article, we will give you a beginner’s guide on how to use underglaze for your pottery projects.
Can You Use Underglaze?
If you’re a ceramics enthusiast, you’ve probably heard of underglaze, but using it can seem intimidating if you’ve never tried it before. The truth is that underglaze can open up a whole new world of creativity and design possibilities in your pottery. Underglaze allows you to add intricate patterns, bold colors, and even photographic images to your work. It’s easy to apply and allows you to layer colors for a stunning effect.
So, if you’re feeling adventurous, try underglaze and see how it can transform your pottery into true works of art!
Why Should You Use Underglaze?
If you’re looking for a way to take your pottery to the next level, underglaze is definitely worth considering. Underglaze is a type of ceramic coloring applied to pottery before it’s glazed and fired, creating a vibrant, permanent, long-lasting surface design. But why use underglaze instead of other types of ceramic coloring, like glaze or slip? For one, underglaze is incredibly versatile.
Because it’s applied before the glaze, you can use it to create intricate designs and patterns that wouldn’t be possible with other types of coloring. Underglaze comes in a wide range of colors and finishes, so you’re sure to find the perfect shades to suit your tastes and style. Whether you’re a seasoned pottery pro or just starting out, using underglaze is a great way to bring your pieces to life.
The Beginner’s Guide on How to Use Underglaze
Step 1: Understand the Different Types of Underglaze
Before you start using underglaze, you should understand the different types available in the market. There are two main types of underglaze: liquid and pencil. Liquid underglaze comes in a bottle and can be applied with a brush or sponge. On the other hand, the pencil underglaze comes in a stick form and can be used to draw intricate designs on the pottery surface. Knowing the different types will help you choose the best suits your project.
Step 2: Apply Underglaze to Greenware or Bisqueware
One of the great things about underglaze is that it can be applied to greenware or bisque ware. If you are working with greenware, apply the underglaze before the first firing. If you use bisque ware, you can apply the underglaze either before or after the first firing. You can also choose to apply multiple coats of underglaze to achieve the desired effect. Before applying the underglaze, ensure your pottery’s surface is clean, dry, and free of any dust or debris.
Step 3: Create Your Designs with Underglaze
Underglaze offers endless possibilities for your design options. You can use a brush, stencil, or sponge to create patterns and textures on the pottery surface. If you want a more precise design, you can use pencil underglaze to draw your design before coloring it in with liquid underglaze. You can also mix different underglaze colors to create a custom color palette that suits your project.
Step 4: Fire Your Pottery
After you have applied the underglaze, you will need to fire your pottery in a kiln. The firing temperature will vary depending on the type of pottery and underglaze you use. Follow the manufacturer’s instructions for firing your pottery, as over or under-firing can affect the final result. After firing, your pottery will have a beautiful, durable finish lasting for years.
Step 5: Finish the Pottery
Once your pottery is fired and cooled, add a clear glaze over the underglaze for a glossy finish. This step is optional and can be skipped for a matte finish. If you choose to use a clear glaze, follow the appropriate firing instructions for the type of glaze used. You can also leave your pottery without a clear glaze, especially if you use pencil underglaze for a more detailed design.
Step 6: Experiment and Have Fun
Using underglaze allows for experimentation and creativity. Don’t be afraid to try out new techniques and mix different colors to create unique designs. The more you use underglaze, the better you will become at controlling its application and achieving your desired results.
Step 7: Practice Makes Perfect
Like any skill, using underglaze requires practice. Don’t be discouraged if your first few attempts don’t turn out as expected. Keep practicing and experimenting to improve your technique and achieve desired results. With time and patience, you will become an expert at using underglaze to enhance your pottery projects.
Enjoy the process and have fun with it! Finally, always remember to follow proper safety precautions when working with underglaze and kilns. Wear protective gear and ensure proper ventilation in your workspace. Now go forth and create beautiful designs with underglaze!
5 Considerations Things When You Need to Use Underglaze
1. Type of Clay
The type of clay you are using will greatly impact the success of your underglaze application. Some clays may not be compatible with certain underglazes, resulting in cracking or flaking after firing. It is important to test your underglaze on a sample piece of clay before applying it to your final project.
2. Application Method
There are various ways to apply underglaze, including brushing, dipping, and spraying. Each method will produce a different effect and may require different techniques for achieving the desired result. For example, brushing may result in more opaque coverage, while spraying can create a more even and translucent finish.
3. Firing Temperature
Underglazes have specific firing temperatures that must be followed for optimal results. If fired at too low of a temperature, the colors may appear dull or muted. On the other hand, firing at too high of a temperature can cause the colors to run or become distorted.
4. Layering Techniques
One of the unique qualities of underglaze is its ability to be layered for depth and dimension in ceramic pieces. However, it is important to consider how each layer will react during firing and if any glazes will be applied on top. Experimenting with different layering techniques can lead to beautiful and unexpected results.
5. Durability
When using underglaze on functional pieces such as mugs or plates, it is important to consider its durability after firing. Some underglazes may not hold up well with frequent use or washing, so it is important to choose one that is suitable for your intended purpose.
Benefits of Using Underglaze
Many potters and ceramic artists swear by the use of underglaze in their work. Not only does it allow for a wider range of color options, but it also provides a smooth, opaque finish that glazes often cannot achieve. Underglaze is perfect for intricate designs and fine details, as it can be easily applied with a brush or sponge.
Plus, it can be layered and blended to create unique effects. Another advantage of underglaze is that it is less likely to run or drip during firing than traditional glazes. Adding underglaze to your pottery toolkit can greatly enhance your artistic abilities and bring your pieces to the next level.
4 Common Mistakes People Make When Trying to Use Underglaze
1. Not Properly Preparing the Surface
One common mistake people make when using underglaze is not properly preparing the surface they will be applying it to. Underglaze works best on a smooth, clean surface, so it’s important to make sure any dust, debris, or previous glazes are removed before applying the underglaze. This can be done by wiping the surface with a damp sponge or using a clay scraper to gently scrape away any imperfections.
2. Applying Too Thickly
Another mistake people make is applying the underglaze too thickly. Underglaze is meant to be applied in thin layers, as it can become runny and lose its vibrant color if applied too thickly. It’s best to apply multiple thin layers and allow each layer to dry completely before adding another one.
3. Not Allowing Enough Drying Time
Underglaze needs time to dry completely before being fired in the kiln. Many people make the mistake of not allowing enough drying time between layers or before firing, which can cause the underglaze to crack or peel off during firing. It’s important to follow the manufacturer’s recommended drying times and ensure that each layer is completely dry before adding another one.
4. Using the Wrong Type of Brush
Using the wrong type of brush can also lead to mistakes when using underglaze. It’s important to use a soft-bristled brush specifically designed for underglazes, as this will help create a smooth and even application without leaving visible brushstrokes. Using a stiff-bristled brush or one meant for other types of glazes may result in an uneven or streaky appearance on your finished piece.
Conclusion
Using underglaze for pottery is a fun and creative way to add color and personality to your projects. With a little bit of practice, you can use underglaze to create intricate designs and patterns that will make your pottery stand out. Just remember to choose the right type of underglaze, follow the instructions carefully, and have fun experimenting with different design options.
