Bubble Glazing Pottery: An In-Depth Guide to a Unique Ceramic Technique

Bubble glazing is an innovative and captivating ceramic technique that creates a unique, bubbly texture on pottery pieces. This fascinating approach to pottery decoration involves the application of glaze using bubbles, which burst and leave behind a one-of-a-kind pattern on the ceramic surface.

This comprehensive guide will explore the history of bubble glazing, how to bubble-glaze pottery, tips and tricks for successful bubble glazing, and inspiration for incorporating this technique into your ceramic art.

The History of Bubble Glazing

While the exact origins of bubble glazing remain unknown, it is believed that the technique has been practiced for centuries in various cultures worldwide. The earliest examples of bubble-glazed pottery date back to China’s Tang Dynasty (618-907 CE). Over time, the technique spread to other regions, including Japan, Korea, and Europe, where local ceramic artists adapted and refined it.

How to Bubble Glaze

The process of bubble glazing involves several steps, including preparing the glaze, creating the bubbles, and applying the bubbles to the pottery. Here is a step-by-step guide to the bubble glazing process:

Preparing the Glaze

The first step in bubble glazing is to prepare the glaze. This involves selecting a suitable glaze for your pottery piece and mixing it to the desired consistency. The glaze should be thin enough to form bubbles but thick enough to adhere to the pottery surface. Most commercially available glazes can be used for bubble glazing, but some experimentation may be necessary to achieve the desired effect.

Creating the Bubbles

Once the glaze is prepared, the next step is to create the bubbles. There are several methods for creating bubbles, including using a straw, a bubble wand, or an air compressor. Some artists also create bubbles by blowing air directly into the glaze using their mouths. The choice of method will depend on the artist’s preference and the desired size and density of the bubbles.

Applying the Bubbles

With the bubbles formed, it’s time to apply them to the pottery piece. The ceramic surface should be clean and free of any dust or debris. The bubbles can be applied by gently touching them to the pottery surface or allowing them to drop onto the piece from above. As the bubbles burst, they leave behind a glaze pattern in the bubble’s shape.

Firing the Pottery

After applying the bubble glaze, the pottery piece is left to dry. Once dry, the piece is fired in a kiln following the glaze manufacturer’s recommended firing schedule. The firing process will cause the glaze to melt and fuse to the ceramic surface, creating a permanent and unique bubble pattern.

Tips and Tricks for Successful Bubble Glazing

To achieve the best results with bubble glazing, consider the following tips and tricks:

Experiment with Glaze Consistency

The consistency of the glaze plays a crucial role in the success of bubble glazing. The glaze may not form bubbles or adhere appropriately to the pottery surface if it is too thick. If the glaze is too thin, the bubbles may be too fragile and burst before they can be applied. Experiment with different glaze consistencies to find the best one for your bubble glazing project.

Control Bubble Size and Density

The size and density of the bubbles will affect the final appearance of your bubble-glazed pottery. Smaller bubbles create a more delicate and intricate pattern, while larger bubbles produce a bolder and more dramatic effect. Adjust the bubble size and density by changing the method of bubble creation or by altering the airflow.

Multiple Layer Glazes

Consider layering multiple glazes for a more complex and visually exciting bubble glaze pattern. This can be achieved by applying one bubble glaze color, allowing it to dry, and then applying a second bubble glaze color on top. Experiment with different color combinations and layering techniques to create a unique, eye-catching design.

Combine Bubble Glazing with Other Techniques

Bubble glazing can be combined with other pottery decoration techniques to add depth and variety to your ceramic art. For example, you can use underglaze or slip decoration beneath the bubble glaze to create an exciting contrast between the bubble pattern and the underlying design. Alternatively, you can apply bubble glazing to specific areas of a pottery piece and use other techniques, such as sgraffito or brushwork, to decorate the remaining areas.

Inspirational Ideas for Bubble Glazed Pottery

The possibilities for bubble-glazed pottery are virtually endless, limited only by your imagination and creativity. Here are some inspirational ideas to spark your artistic vision:

Create a Sea-Inspired Design

The bubbly texture of bubble-glazed pottery lends itself well to sea-inspired designs. Use shades of blue, green, and white to create an oceanic color palette and apply bubble glaze in wave-like patterns to evoke the feeling of water and surf.

Experiment with Abstract Patterns

Bubble glazing naturally creates abstract patterns on the pottery surface. Embrace the unpredictable nature of this technique by experimenting with different glaze colors and bubble sizes to produce an array of abstract designs.

Incorporate Bubble Glaze into Functional Pottery

While bubble glazing is often used for decorative purposes, it can be incorporated into functional pottery pieces. Consider adding bubble glaze accents to mugs, bowls, or plates to add artistic flair to your everyday tableware.

Use Bubble Glaze as a Background for Detailed Decoration

The unique texture of bubble-glazed pottery can serve as an exciting background for more detailed decoration. Apply bubble glaze to the entire surface of a pottery piece, then use other techniques, such as sgraffito or brushwork, to add intricate designs on top of the bubbly texture.


Bubble glazing is a versatile and captivating pottery technique that can add an exciting visual element to your ceramic art. With its unique texture and endless design possibilities, bubble glazing offers a world of creative exploration for novice and experienced pottery artists. You can incorporate this fascinating technique into your pottery creations by understanding the history, process, and various tips and tricks for successful bubble glazing.

Frequently Asked Questions (FAQs)

Can you bubble glaze with underglaze?

Yes, you can use underglaze for bubble glazing. However, the results might be slightly different from using a traditional glaze. Since underglazes are typically less fluid than glazes, they might create a more subtle bubble pattern on the pottery. Experimenting with different underglaze consistencies and application techniques is essential to achieve the desired bubble effect.

How to make bubble glazing on pottery?

  1. Prepare the glaze: Choose and mix it to the desired consistency.
  2. Create the bubbles: Use a straw, bubble wand, or air compressor to create bubbles in the glaze.
  3. Apply the bubbles: Gently touch the bubbles to the pottery surface or let them drop onto the piece. The bubbles will burst, leaving a unique pattern on the ceramic surface.
  4. Allow the glaze to dry, and fire the pottery following the glaze manufacturer’s recommended firing schedule.

Why does underglaze bubble?

Underglaze may bubble for various reasons, including over-application, uneven drying, contamination, or incompatibility with the glaze or clay body. Additionally, improper firing schedules or temperatures can cause trapped gases or moisture to form bubbles during the firing process. To prevent bubbling, ensure proper application, compatibility of materials, and adhere to recommended firing schedules.
