Did You Know?
1. Did you know that the drying time for glaze between coats can vary depending on the type of glaze? For example, underglazes tend to dry faster than traditional glazes, often requiring only 10-15 minutes between coats.
2. Some glazes containing certain metallic oxides may require longer drying times between coats. This is because those oxides have a slower drying rate, allowing the glaze to develop a richer and more vibrant color as it dries.
3. If you’re in a rush and need to speed up the drying process between coats, you can use a hairdryer on a cool setting to gently blow air over the glazed surface. Just make sure to maintain a safe distance to avoid any unwanted effects.
4. The thickness of the glaze can also affect the drying time between coats. Thicker glaze layers tend to dry slower, so it’s crucial to consider the desired thickness of your glaze when planning the drying time between coats.
5. It’s important to note that different atmospheric conditions can affect the drying time of glaze. Higher humidity levels, for instance, tend to prolong the drying process, while low humidity can expedite it. Therefore, it’s always advisable to take into account the environmental conditions to ensure optimal drying between coats of glaze.
Choosing Compatible Clay And Glazes
When it comes to glazing pottery, choosing compatible clay and glazes is crucial. Incompatible combinations can lead to issues such as crazing, bubbling, pinholes, and cracking. To prevent these problems, it is recommended to select clay and glazes that are compatible with each other.
To ensure compatibility, it is essential to test-fire both the clay and glaze before glazing large batches of pottery. By test-firing, you can determine if the clay and glaze work well together and if any adjustments need to be made. This step can save you from disappointment and frustration later on.
Proper bisque firing is also important for successful glazing. Bisque firing is typically done at cone 06 to 04, with cone 04 being the commonly recommended temperature. This firing temperature helps eliminate organic materials and gases from the clay, providing a clean surface for the glaze to adhere to. It is important to note that different clays require different bisque firing temperatures, so it is crucial to follow the manufacturer’s recommendations.

Proper Bisque Firing Techniques
To achieve the best results when glazing pottery, properly bisque firing is crucial. Bisque firing refers to the initial firing of pottery before glazing. This firing is typically done at cone 06 to 04, with cone 04 being recommended to eliminate organic materials and gases from the clay.
Before bisque firing, it is important to ensure that the pottery is dry and free of any moisture. Any trapped moisture can cause the pottery to crack or explode during the firing process. Once the pottery is dry, it can be loaded into the kiln for bisque firing.
It is crucial to follow proper firing techniques, including ramping up the temperature slowly to avoid thermal shock and allowing the kiln to cool down gradually after firing. These steps help to ensure that the pottery is fired evenly and prevents any cracking or warping.
Additionally, it is important to monitor the kiln temperature closely during bisque firing to ensure that it reaches the desired firing temperature. Using pyrometric cones is a reliable method to accurately measure the temperature inside the kiln.
Preparing The Pottery For Glazing
Before glazing pottery, proper preparation is essential to ensure a smooth and successful glazing process. One important aspect is keeping resist spots off the pottery to ensure proper glaze adherence. It is crucial to avoid touching the pottery with lotions, oils, or natural oils from hands, as these can create resist spots that prevent the glaze from adhering.
Another important step in preparing pottery for glazing is sanding bisque ware with sandpaper. This helps to smooth out any rough edges and create a surface that is ready to accept the glaze. It is important to wear a dust mask and keep the studio dust-free during this process to avoid inhaling any dust particles.
Cleaning bisque ware with a damp sponge before glazing is also advised. However, it is important to avoid submerging the pottery in water, as this can lead to the accumulation of dust on the surface. Instead, gently wipe the pottery with a damp sponge to remove any dirt or dust particles.
Taking notes and photographing the glazing process is also recommended for future reference. This helps to keep a record of the techniques and glaze combinations used, allowing you to recreate successful results and avoid repeating any mistakes.
Applying The Glaze Properly
The application of glaze plays a crucial role in achieving a perfect finish on pottery. Choosing the right brush for glazing is important, and options include hake brushes or fan brushes. These brushes allow for precise application and control over the glaze.
One of the biggest challenges when brushing on glazes is streaking. Streaking occurs when coats are applied too thin, resulting in uneven and unsightly surfaces. To avoid this, it is important to load the brush with enough glaze for proper application onto the pottery.
Changing the direction of brush strokes with each coat is another helpful technique to even out the thickness of the glaze and prevent streak marks. By alternating the direction of the brush strokes, you can ensure that the glaze is applied evenly, resulting in a smooth and consistent finish.
It is also important to keep the handle of the brush clean to prevent any drippage on the pottery. Any drips or smudges can affect the final result and create imperfections in the glaze layer.
Having two rinse bowls with sponges is recommended to keep the bottom of the pottery and the brush clean. This prevents any glaze from mixing on the pottery surface and ensures that each application is clean and precise.

- Alternate the direction of brush strokes with each coat
- Keep the handle of the brush clean
- Use two rinse bowls with sponges to keep the pottery and brush clean
Drying Time Between Coats Of Glaze
Once the glaze is applied, it is crucial to allow it to dry between coats. This is particularly important for brush glazes, as they tend to take longer to dry compared to dipping glazes.
Allowing sufficient drying time between coats helps to avoid any chances of smudging or disrupting the previous layer of glaze. If the glaze is still wet when another coat is applied, it can mix with the previous layer and result in an uneven and unsatisfactory finish.
The drying time between coats can vary depending on the glaze’s composition and the thickness of the application. It is recommended to follow the manufacturer’s instructions regarding drying times for specific glazes. Generally, it is advisable to wait until the glaze feels dry to the touch before applying another coat.
Additionally, it is important to avoid drying the glaze too quickly by using excessive heat or direct sunlight. Rapid drying can cause the glaze to crack or flake off, compromising the final result. It is important to allow the glaze to dry naturally and evenly to ensure a durable and attractive finish.
In conclusion, achieving a perfect glaze finish on pottery requires careful consideration and attention to detail. By selecting compatible clay and glazes, properly bisque firing, preparing the pottery, applying the glaze properly, and allowing sufficient drying time between coats, beginners can ensure successful results.
