How to Mix Pottery Glazes
To mix pottery glazes, you have several options for tools and techniques.
Potters can use gloved hands or a large kitchen whisk to manually mix the glazes.
However, there are also tools available that can make the mixing process easier and faster.
One option is to use attachments for a hand-held drill, which come in two choices.
Glaze-specific attachments are expensive but designed to reduce air in the glaze and handle its density.
On the other hand, paint mixers, also known as paint stirrer attachments, are cheaper but may add some air to the glaze, which can affect its application to pottery.
Regardless of the mixing method you choose, it is important to maintain a consistent ratio of 9 parts water to 10 parts glaze, and to thoroughly mix all the ingredients until there are no lumps.
Sieving the glaze after mixing is also recommended to ensure a smooth application and finish.
Overall, mixing your own pottery glazes allows for consistent results, the ability to achieve desired colors, and cost-effectiveness.

Did You Know?
1. Ancient Roman potters used lead oxide to produce a stunning red glaze called “terra sigillata,” which was widely popular in the Mediterranean region.
2. The ancient Egyptians developed an innovative technique known as “faience” to mimic the appearance of precious stones in pottery glazes. This process involved using crushed quartz, alkaline salts, and various minerals to achieve vibrant colors.
3. During the Ming dynasty in China, cobalt oxide was introduced in pottery glazes, giving birth to the iconic blue and white porcelain style that still captivates collectors and enthusiasts today.
4. While most glazes have a glossy or matte finish, a rare type known as “crystalline glaze” creates a mesmerizing effect by forming tiny, colorful crystals on the surface of the pottery when fired under specific conditions.
5. The “raku” technique, originating from Japan in the 16th century, involves removing pottery from the kiln while it is still red-hot and rapidly cooling it. This process leads to unique, unpredictable patterns and crackling effects on the glaze, making each piece one-of-a-kind.
Mixing Pottery Glazes By Hand Or With A Whisk
Mixing pottery glazes can be done by hand using gloved hands or a large kitchen whisk. This method is suitable for small batches of glaze and provides good control over the mixing process. When mixing by hand, it is crucial to ensure that the glaze is well-mixed to achieve consistent results.
Alternatively, there are tools available that can make the mixing process easier and faster. These tools can save time and effort, especially when dealing with larger quantities of glaze. They are particularly useful for potters who work on a larger scale or have physical limitations that make manual mixing challenging.
Tools To Make Glaze Mixing Easier And Faster
One tool that potters can use to make glaze mixing easier is a hand-held drill with attachments specifically designed for mixing glazes. These attachments come in different types and sizes, allowing potters to choose the one that best suits their needs.
Choosing The Right Mixer Drill Attachments For Glaze Mixing
When it comes to choosing the right mixer drill attachments for glaze mixing, potters have two options.
-
Glaze-specific attachments: These attachments are designed with features that help reduce air in the glaze and handle its density effectively. They may be more expensive but can provide better results in terms of glaze quality.
-
Paint mixers (also known as paint stirrer attachments): These attachments are cheaper and more readily available. However, they may introduce some air into the glaze during the mixing process, which can affect its application to pottery.
When making a decision between these options, potters should consider the specific requirements of their glaze and their desired outcomes.
Pros And Cons Of Glaze-Specific And Paint Mixer Attachments
The choice between glaze-specific and paint mixer attachments for glaze mixing depends on several factors. Glaze-specific attachments offer the advantage of handling glaze density and reducing air in the mixture, resulting in a smoother application and finish. However, these attachments tend to be more expensive.
On the other hand, paint mixer attachments are more affordable but may introduce some air into the glaze, which can affect its application to pottery. This air incorporation can lead to bubbles or other imperfections in the glaze. Therefore, potters should carefully consider the pros and cons of each attachment type before making a decision.

Advantages Of Mixing Your Own Glaze
Mixing your own glaze offers several advantages. First and foremost, it allows potters to achieve consistent results. By controlling the glaze composition and mixing process, potters can replicate desired colors and effects. This consistency is especially important when working on a specific project or building a cohesive body of work.
Another advantage is the cost-effectiveness of mixing your own glaze. Purchasing pre-mixed glazes can be expensive, especially if you are using large amounts or unique formulations. By sourcing and mixing your own glaze materials, you have greater control over costs and can potentially save a significant amount of money in the long run.
Materials And Steps For Mixing Pottery Glazes
To mix pottery glazes, you will need the following materials:
- A container with a lid
- Dry glaze
- A scale
- Water (preferably distilled or DI water)
- A sieve
The container should be large enough to hold the desired amount of glaze and have a tight-fitting lid to prevent evaporation.
The first step in mixing glaze is to place the container on a scale and add water. The ratio of water to glaze generally recommended is 9:10, meaning 9 parts water to 10 parts dry glaze by weight. Once the water is added, tare the scale to zero and slowly pour the dry glaze into the container until the desired weight is reached.
It is important to ensure that all the dry material is soaked with water until it is completely wet. This can be achieved by shaking, stirring, or plunging the mixture. These actions help break up any dry clumps and thoroughly incorporate the water into the glaze.
After mixing, it is highly recommended to sieve the glaze to eliminate any remaining chunks. This step ensures a smoother application and finish, as well as removes any impurities or foreign particles. The size of the sieve used depends on the size of the glaze operation, with larger operations typically requiring larger sieves.
In conclusion, mixing pottery glazes can be done by hand or with the assistance of tools like hand-held drills with mixer attachments. The choice of attachment type depends on the desired outcome and the specific requirements of the glaze. By mixing your own glaze, you can enjoy the benefits of consistent results, cost-effectiveness, and the ability to achieve the desired color and finish.
Remember to:
- Follow the recommended ratio
- Thoroughly wet the dry material
- Sieve the glaze for optimal results
Happy glaze mixing!
