This is a purple clay teapot, a traditional tea set produced in Yixing City, Jiangsu Province, China.  
Zisha teapots are renowned for their unique material and craftsmanship. Their surface is typically unglazed, allowing them to absorb the tea's aroma and enhance the tea's flavor.  
The clay used in a purple clay teapot contains a variety of natural minerals, such as quartz, kaolin, feldspar, mica, and hematite.  
The surface of a purple clay teapot may have tiny black spots (iron molten), white spots (mica), small pits (sand skipping), and small bumps (bursts), all of which are hallmarks of authentic purple clay teapots.  
Zisha teapots are often considered works of art and passed down from generation to generation as heirlooms.
