The Chinese name 中汉瓦 literally reads as “middle/medium Han tile.” This exact term is not a widely recognized, standard teapot form in classical catalogs, so its precise historical pedigree is ambiguous. Read literally, however, it suggests a medium‑sized teapot inspired by Han (汉) dynasty tile motifs or by the planar, slab‑like geometry of roof tiles (瓦).

Brief historical context: tiles and tile motifs have been used in Chinese ceramics and architectural ornament since antiquity — Han dynasty (206 BCE–220 CE) decorative vocabulary in particular is often revisited by later potters. True teapot production, as a distinct vessel type, flourished from the Ming and Qing eras and became highly developed in Yixing (Zisha) ware from the 17th century onward. Contemporary and revivalist makers frequently borrow ancient motifs (including Han forms and tile geometry) and translate them into teapot designs.

Shape note: a “tile” teapot would typically read as compact and low in profile, with planar or faceted surfaces, a relatively flat lid, and a handle/spout integrated with the angular lines. Finished in unglazed stoneware or Zisha clay, such a piece emphasizes form and texture rather than ornate surface decoration.

If you can provide a photo, I can give a more specific identification and description.
