Dry brushing is a popular underglaze technique, but there are certain situations when it may not be suitable or effective.
Highly Porous Clay
Dry brushing may not yield the desired results on extremely porous clay, as the underglaze may be absorbed too quickly and not produce the intended effects.
For covering large areas, dry brushing can be time-consuming and may lead to uneven coverage. Other underglaze techniques, such as brushing or dipping, might be more efficient.
Very Dark Colors
Dry brushing with very dark underglaze colors on a light clay body may result in a dusty appearance rather than the intended subtle texture.
While dry brushing is a valuable technique, understanding its limitations and considering the specific characteristics of your clay and design will help you determine when it’s the best choice.
