Airbrushing underglaze onto pottery is a popular technique for adding intricate designs, patterns, and color to ceramic pieces. This method involves using an airbrush to spray fine layers of underglaze onto the surface of the clay before firing it in a kiln. The result is a smooth and precise application of pigments that can create stunning effects on pottery.
In this guide, we will discuss the step-by-step process of how to use airbrushing underglaze onto pottery, as well as provide tips and tricks to help you achieve professional-looking results. If you’re new to airbrushing or just looking for some guidance, this guide is perfect for you. So let’s get started!
What is Underglaze?
Underglaze is a type of ceramic pigment that is applied to the surface of clay before firing. It typically comes in liquid form and can be found in a wide range of colors. Underglazes are used to decorate pottery by creating intricate designs, patterns, or even solid blocks of color on the surface.
Unlike glazes which create a glossy finish when fired, underglazes retain their matte finish after firing. This makes them ideal for creating detailed designs and patterns on pottery, as well as for layering different colors to achieve unique effects.
11 Best Ways on How to Use Airbrushing Underglaze Onto Pottery
1. Prepare Your Underglaze and Airbrush:
Before you start airbrushing, it’s important to make sure your underglaze is thoroughly mixed and ready to use. Shake the bottle well or stir the liquid if necessary to ensure a smooth consistency. Preparing your airbrush involves cleaning it and making sure it is in good working condition. This includes checking the nozzle, needle, and air pressure to ensure a fine spray. If you’re new to airbrushing, it’s a good idea to practice on a test piece or scrap clay before moving on to your actual pottery.
2. Choose the Right Clay and Bisque:
Not all clays are suitable for airbrushing underglaze. Some may be too porous and absorb the pigments unevenly, while others may have a rough surface that can cause clogs in your airbrush. It’s best to choose a smooth, fine-grained clay with a low absorption rate for the best results.
Also, make sure your pottery is fully bisque-fired before airbrushing. Bisque firing strengthens the clay and prepares it for glazing or underglaze application. If you’re applying underglaze to greenware (unfired clay), make sure to handle it with care to avoid any damage.
3. Prepare Your Workspace:
Before you start airbrushing, make sure your workspace is clean and well-ventilated. Lay down a drop cloth or newspaper to protect your work surface from overspray. It’s also a good idea to have paper towels or rags on hand to clean up any spills or drips. Preparing your workspace will help you stay organized and focused while airbrushing. If possible, set up your airbrush near a window or fan to help with ventilation.
4. Dilute Your Underglaze:
For optimal results, it’s recommended to dilute underglaze before using it in an airbrush. This helps create a smoother spray and prevents clogs in your airbrush. The amount of water you add will depend on the brand and thickness of your underglaze. It’s a good idea to start with a 1:1 ratio (equal parts water and underglaze) and adjust from there if needed. This may require some trial and error to find the right consistency for your specific underglaze and airbrush.
5. Test Your Airbrush:
Before applying underglaze to your pottery, it’s important to test your airbrush on a scrap piece of clay or paper. This will help you determine the speed, pressure, and angle needed for a smooth spray. It’s also a good opportunity to make any necessary adjustments before moving on to your pottery. If you’re using multiple colors, it’s recommended to test each one individually to ensure they are all spraying correctly.
6. Start with Light Layers:
When applying underglaze with an airbrush, it’s best to start with light layers rather than heavy coats. This will help prevent dripping or oversaturation of the clay surface. You can always add more layers for a deeper color, but it can be difficult to fix mistakes caused by too much underglaze. Remember to let each layer dry completely before adding more. This will also help prevent smudging or blending of colors.
7. Play with Different Techniques:
One of the great things about airbrushing underglaze is that it allows for a lot of creative freedom and experimentation. Don’t be afraid to play with different techniques such as masking, stenciling, and layering to create unique designs and patterns on your pottery. You can also try using different airbrush tips and settings to achieve varying effects. The most important thing is to have fun and let your creativity flow.
8. Clean Your Airbrush Regularly:
To maintain the quality of your airbrush and prevent clogs, it’s important to clean it regularly. This includes flushing out any remaining underglaze with water after each use. For a more thorough cleaning, you can disassemble the airbrush and clean each part with a brush and cleaning solution. It’s also recommended to clean your airbrush before switching between different underglaze colors.
9. Add Detail with Brushes:
Even though airbrushing is great for creating smooth and precise layers of underglaze, it can be difficult to achieve intricate details. To add small details or touch-ups to your design, use a fine-tipped brush with your underglaze. This will give you more control and precision for those final touches. Adding details with brushes is also a great way to add texture and depth to your airbrushed design.
10. Consider Firing Options:
After airbrushing underglaze onto your pottery, you have the option of firing it in different ways depending on the look you want to achieve. For a more traditional matte finish, fire at the recommended temperature for your underglaze. For a glossy finish, consider applying a clear glaze over the underglaze and firing it again. You can also try experimenting with different firing temperatures or combining underglazes to create unique effects.
11. Practice and Have Patience:
Like any skill, airbrushing underglaze onto pottery takes practice and patience to master. Don’t be discouraged if your first attempts don’t turn out exactly as you hoped. Take the time to practice and experiment with different techniques until you find what works best for you. With patience and persistence, you’ll be able to create beautiful airbrushed pottery that showcases your unique style and creativity.
Following these tips and techniques will help you achieve stunning results when airbrushing underglaze onto your pottery. Remember to always work in a well-ventilated area, choose the right clay and bisque, dilute your underglaze, test your airbrush, play with different techniques, clean regularly, add details with brushes, consider firing options, and most importantly – have patience and practice! With these skills, you’ll be able to add an extra level of creativity and artistry to your pottery projects.
