Which is more expensive, purple sand engraving or overlapping color painting?

Zisha lettering is more expensive. Because some well-known masters transplanted the traditional calligraphy and painting of China into the teapot, the teapot had a ceramic handicraft integrating China's calligraphy, painting, literature, history, epigraphy, sculpture and many other elements.

Therefore, purple sand seal cutting is deeply loved by people from all walks of life, especially literati and collectors. In particular, the famous purple sand sculpture is highly respected and expensive.
