The exact name "黄泥汉瓦" is not a widely documented, standard teapot form in the major reference lists, so the identification is somewhat ambiguous. Literally it reads "yellow clay Han‑tile": 黄泥 (huáng ní) = yellow clay (a warm, yellow‑toned pottery body used by various Chinese potters) and 汉瓦 (hàn wǎ) = Han (dynasty) tile. Pottery and teapot forms in China are often named after everyday objects or historical motifs, so this name most likely refers to a teapot whose profile or lid echoes the shape of a Han‑dynasty roof tile.

Brief history/context: Many classic teapot shapes were developed and named by Yixing and other Jiangnan potters from the late Ming into the Qing and later periods, drawing inspiration from architecture, nature and antiquities. Using a yellowish clay body has long been part of regional ceramic practice; such clays produce a warm tone and develop a soft patina with use.

Shape note: Expect a low, compact body with a flattened or gently arched top resembling a tile, a simple fitted lid (sometimes with a raised ridge), restrained ornament, short functional spout and a plain loop or C‑handle. The form is typically small in volume and suited to gongfu brewing. If you can share a photo, I can offer a more specific identification.
