窑 (yáo): Kilno

This old kiln has been firing for over a century, its walls baked red by the flames; the villagers have relied on it for generations to make bricks and tiles.

After the ceramic workers stack the unfired pieces in the kiln, they must strictly control the temperature; otherwise, a whole kiln's worth of porcelain could be ruined.

Archaeologists discovered a well-preserved ancient kiln at the site; from the fragments unearthed inside the kiln, they can infer the pottery-making techniques of that time.

To produce blue-and-white porcelain, the craftsmen kept adding firewood to the kiln day and night, not stopping until the kiln fire reached the required temperature.

This brick factory uses a new type of eco-friendly kiln, which not only reduces smoke and dust emissions but also improves the firing quality of the bricks.
