Using underglaze on wet clay is possible but can present challenges due to the moisture content and pliability of the clay.
Application Challenges
Applying underglaze to wet clay can lead to smudging, bleeding, or distortion of the design as the moisture from the clay interacts with the underglaze.
Techniques
If you choose to use underglaze on wet clay, consider techniques that work well with the moisture, such as brushwork, slip trailing, or stamping.
Surface Treatment
Underglaze applied to wet clay may have a different appearance compared to application on leather-hard or bone-dry clay. The moisture content can affect color and absorption.
Conclusion
While underglaze can be used on wet clay, it requires careful consideration of application techniques and an understanding of how the moisture will interact with the underglaze.
