In the 9th century, mass ceramics trade items in Southeast Asia were primarily produced in areas such as present-day Vietnam, Indonesia and Thailand. These ceramics were produced using local materials, such as clay, and were fired in kilns using wood or charcoal as fuel. The ceramics were known for their bright colors and intricate designs, which were influenced by the cultural traditions of the area. Some examples of mass ceramic trade items from Southeast Asia in the 9th century include:

Vietnamese celadon ceramics: These were produced in the northern regions of Vietnam and were known for their green glaze and delicate floral designs.

Srivijayan ceramics: These were produced by the Srivijayan Empire, which was centered in present-day Sumatra and was a major maritime power in Southeast Asia during the 9th century. These ceramics were known for their geometric designs and were traded throughout the region.

Thai Sawankhalok ceramics: These were produced in present-day Sukhothai province of Thailand and were known for their brown glaze and intricate designs.

Majapahit ceramics: These were produced by the Majapahit Empire, which was centered in present-day Java. These ceramics were known for their vivid colors and complex designs.

It's important to note that the 9th century is a very broad time frame and it's hard to find specific information about ceramics trade in Southeast Asia during that period, but the ceramics trade was certainly taking place and it was an important part of the economy for many Southeast Asian kingdoms and empires.
