In the early period of the 20th century, Longhai railway was built through the Mang mountains, north of Luoyang city, Henan Province, where the graveyards of the Han and Tang dynasties were located. When these tombs were excavated, lots of colorful pottery was found. However, the find did not received much attention from the media or public at the time. Collectors thought they were just common funeral objects and were ill-boding, until a Chinese antiquities collector, Luo Zhenyu (1866 - 1940) saw their chips in a market.

To Luo’s surprise, there was no information about this kind of pottery in historical records. While experts were puzzling over these objects, they were named “Tang tri-colored glazed pottery” among the people.

Tang tri-colored glazed pottery was very popular in the Tang Dynasty (618-907). It is a low-melting glazed pottery that is made by adding metallic oxides to the colored glaze and calcifying the object to create different colors, namely the predominant red, white and green.

The chemicals in the glaze change gradually in the firing process, creating a variegated effect with a majestic and elegant artistic attraction.
