The Purple Sand Museum is right next to the Nianhua Scenic Area and there is a Purple Sand Museum. The Purple Sand pot has been fried very hot in recent years, so I plan to go in and explore the truth. Anyway, I just came into the museum and just met the teacher who was teaching how to make a Purple Sand pot. The first step is to make a piece of purple sand mud into a regular long strip called purple sand ore, Ya called "rich earth", commonly known as "tianqing mud", "red brown mud", "bottom trough clear mud", "big red mud", for the main raw materials for making purple sand pot (ware). Deeply hidden hundreds of meters below the Huanglong Mountain rock formation, between the "jiali" mineral layer. In Yixing, purple sand mud can only be found in the clay mines within the Dingyu area. Then the good purple sand mud cutting museum also copied the old cave caves in Yixing directly.
