Getting bright underglaze colors on your pottery can elevate your ceramic projects to a new level of vibrancy and appeal. To achieve this, it’s essential to understand the right techniques and materials. This guide will walk you through the steps to ensure your underglazes pop with color.
What Are Underglazes?
Underglazes are ceramic materials used to add color and design to pottery before it is glazed and fired. They are versatile and can be applied to both greenware and bisque-fired pottery. Unlike glazes, underglazes do not contain glass-forming components, which means they don’t melt during firing, allowing for precise and detailed designs.
How to Apply Underglaze for Bright Colors
1. Select the Right Underglaze
Choosing high-quality underglaze is crucial. Look for brands known for their vibrant colors and consistent results. Amaco Velvet Underglazes and Duncan Concepts are popular choices among potters.

2. Prepare Your Pottery Surface
The surface of your pottery should be smooth and clean. Any dust or debris can affect the adherence of the underglaze.
- Greenware: Sand lightly to smooth out imperfections.
- Bisque-fired Pottery: Wipe with a damp sponge to remove dust.
3. Apply Underglaze Evenly
Using the right tools can make a significant difference in application:
- Brushes: Use soft, synthetic brushes for even coverage.
- Sponges: Ideal for larger areas or creating textures.
- Sprayers: For a smooth, even coat over large surfaces.
Apply multiple thin layers, allowing each to dry before adding the next. This builds depth and ensures even coloration.
4. Test Firing
Before committing to a full project, test fire a small sample. This helps you understand how the underglaze will look after firing.
5. Use a Transparent Glaze
After applying underglaze, cover it with a clear glaze. This step protects the colors and adds a glossy finish, enhancing brightness.

Tips for Enhancing Underglaze Brightness
- Layer Colors: Experiment with layering different colors to create depth and interest.
- Add White: Mixing a small amount of white underglaze can make colors appear brighter.
- Fire at the Right Temperature: Each underglaze has a recommended firing range. Adhering to this ensures optimal color development.
Common Mistakes to Avoid
- Overloading Brushes: Too much underglaze on the brush can lead to uneven application.
- Skipping Test Firing: Always test fire to avoid unexpected results.
- Incorrect Firing Temperature: This can dull colors or cause underglaze to burn out.

How Do You Make Underglaze More Vibrant?
To make underglaze more vibrant, apply multiple thin layers and ensure each layer is fully dry before applying the next. Using a clear glaze over the underglaze can also enhance its brightness.
Can You Mix Underglaze Colors?
Yes, you can mix underglaze colors to create custom shades. Always test the mixed color on a small piece to see how it looks after firing.
What is the Difference Between Underglaze and Glaze?
Underglaze is used for adding color and design before applying glaze. It does not melt during firing, allowing for detailed designs. Glaze contains glass-forming components and melts to form a shiny, protective layer on pottery.
What Temperature Should I Fire Underglaze?
The firing temperature for underglaze depends on the specific product. Most underglazes work well in the cone 04 to cone 6 range. Always refer to the manufacturer’s instructions.
Can You Use Underglaze on Greenware?
Yes, underglaze can be applied to greenware. It is often easier to apply and less likely to smudge compared to applying on bisque-fired pottery.
Conclusion
Achieving bright underglaze colors involves selecting quality materials, applying them correctly, and firing at the appropriate temperature. By following the steps outlined in this guide, you can enhance your pottery projects with vibrant, eye-catching designs. For further exploration, consider experimenting with different techniques and materials to find what works best for your artistic vision.
