This process can make use of the coarseness of the sand grains to increase the texture of the surface of the pot body, and can also improve the yield of the purple clay pot.
There are two types of sand mixing. One is sand mixing with the same type of mud, which means adding the same sand as the original mud to make it. This kind of sand mixing is the most common when making red clay pots. The other method is to mix sand with non-similar mud materials.

2. Reduce production costs
Using the sand conditioning process can improve the yield and thereby reduce production costs. Different clay materials for purple clay teapots have different degrees of shrinkage. Among them, vermilion clay has the largest shrinkage ratio, making it more difficult to make and requires higher time and cost. Therefore, when making a vermilion clay pot, some craftsmen will add half-cooked vermilion mud sand particles to the clay material to reduce the shrinkage of the clay material, thereby increasing the success rate of making pots and thus reducing the production cost.
3. Enhance the breathability of the pot body
When making the pot, add sand to adjust the sand to increase the air permeability of the pot. The quartz component in the purple sand mud is one of the minerals that causes the purple clay teapot to form double pores. Adding sand to the sand increases the quartz component in the pot. This can increase the proportion of pores in the mud and help increase the quality of the pot. Breathability.
In summary, the sand-adjusting process is a common process in making purple clay pots, using different coarse and fine sand grains to make unique purple clay pots.
