"Ay" (硋) is a type of black-glazed ceramic indigenous to the mountainous region of northeastern Fujian, positioned between pottery and porcelain. The site is a century-old traditional Ay kiln built against a hillside, forming an elongated, sloped "dragon kiln." Situated at the village entrance and flanked by open fields, the site exhibits characteristics of a rural handicraft compound: the kiln sits at the center, an old rammed-earth house to the west, a modern brick-and-concrete dwelling to the east, and several stone outbuildings scattered around.
