Understanding Underglaze and Its Interaction with Kiln Shelves
Have you ever anxiously opened your kiln, just to be greeted with the sight of your precious piece stuck firmly to the shelf? This nightmare scenario is often linked to underglaze usage. The good news is, understanding some key aspects of how underglaze interacts with kiln shelves can save you from such heartbreak.
Underglazes are a fantastic way to add vivid color to your pottery, but getting them to work right requires a little bit of know-how. The main concern is often whether underglaze will stick to the kiln shelf, which can occur if certain precautions aren’t taken. For more details on application techniques, check out six different ways to use underglazes with ceramics.
Using Kiln Wash to Protect Your Creations
A simple and effective way to prevent underglaze from sticking is by using kiln wash. Apply a thin layer of kiln wash to your kiln shelves before firing. This acts as a protective barrier, ensuring that if any underglaze does creep off your ceramic piece, it won’t adhere to the shelf. Not only does this protect the shelf, but it also facilitates easy removal of the pieces from the kiln, helping to maintain the integrity of your pottery.
The Importance of Firing Temperature
Temperature plays a pivotal role in how underglazes behave. It’s crucial to ensure that you are firing to the correct temperature as specified by the underglaze manufacturer. Firing at the wrong temperature can either cause the underglaze to underfire or overfire, thus affecting its adhesion to the pottery and kiln shelf. Generally, most underglazes are formulated to be stable at both bisque and glaze firing temperatures, but verifying the specifics for each type ensures you avoid unnecessary mishaps.

Mastering Application Techniques
The application of underglaze is as much an art as creating the ceramic piece itself. Applying underglaze too thickly is a common mistake that can lead to undesirable results, such as the underglaze seeping onto the kiln shelf. A smooth, even application will adhere better to the pottery surface.
- Create a consistent surface by sanding your bisque ware lightly before applying underglaze.
- Apply thin, even coats. Several thin layers are better than one thick one.
- Allow each layer to dry thoroughly before applying the next to prevent smudging and uneven texture.
Using these techniques will not only enhance the aesthetics of your finished piece but will also reduce the risk of sticking.
