The famous series of ceramic treasures created in the Tang dynasty in China are a. celadon B. tri-colored Tang C. white porcelain D. black porcelain.

Test analysis: this small question examines Tang Sancai. Tri-colored pottery in Tang Dynasty is a general term for pottery. Because it was fired in the Tang Dynasty, the most commonly used colors in the works are yellow, green and white, so it is called Tang Sancai. In fact, its colors include blue, ochre, purple and black. On the basis of low-temperature lead glazed pottery technology in Han Dynasty, this kind of colored glazed pottery was successfully made through long-term practice and a new understanding of various raw materials containing non-ferrous metal elements, and experienced a slow firing development process from coarse to fine. Tang Sancai absorbed the characteristics of Chinese painting, sculpture and other arts and crafts, and used decorative patterns in the form of overlapping painting, with rough and powerful lines. In the mutual reflection of colors, the three colors in the Tang Dynasty show magnificent artistic charm. Tang Sancai was mostly used for funerary objects. As funerary objects, its practicality was far less than that of celadon and white porcelain, because of its crisp fetal quality and poor waterproof performance. However, it has great artistic value and is known as the treasure of pottery art.
