Creating hand-built porcelain sculptures with uniform thickness is a delicate art that requires precision and skill. One of the most common challenges is maintaining consistent clay thickness throughout the sculpting process. Uneven drying can lead to cracks or warping, especially in larger pieces. Additionally, the natural variations in hand-rolled clay slabs often result in thicker or thinner sections.

Another issue arises from the artist's technique—applying uneven pressure while shaping the clay can create inconsistencies. Porcelain's fine particle structure also makes it prone to collapsing if walls are too thin or drying too quickly. Proper support structures and controlled drying environments are essential to mitigate these risks.

Finally, the firing process itself can reveal hidden thickness variations as different sections shrink at slightly different rates. Mastering these challenges requires patience, practice, and often specialized tools like calipers or thickness gauges to ensure consistency in every creation.
