Four other clay teapot traditions: Chaozhou, Jianshui, Qinzhou and Taiwan

Why Yixing rules fail on non-Yixing clay teapots#

Field research documents both slab-built and mould-assisted production in contemporary Yixing. Similar shapes can result from different materials and processes; appearance alone does not establish a vessel’s manufacture.

Chaozhou: wheel-thrown red clay#

Chaozhou red clay is used for small wheel-thrown teapots associated with gongfu tea. Although finished pots may be called zhuni, this local material tradition should not be equated with Yixing zhuni. Different ores and prepared bodies are described in the sources.

Jianshui: carved and filled clay#

Follow a single line of Jianshui decoration through the workshop. The potter cuts into the damp body and fills the recess with clay of another colour. Firing and polishing come later. On the finished wall the contrasting line is the exposed filling. (建水紫陶烧制技艺 · Ⅷ-98)

Qinzhou: clay preparation and polishing#

Qinzhou nixing bodies combine clays traditionally described as coming from opposite banks of the Qin River in Guangxi. Fired surfaces are polished to reveal their colour. The east-clay/west-clay distinction explains a preparation tradition; it does not establish one recipe for every pot.

4. Taiwanese teapots: Yingge, Miaoli, rock-mineral clay and wood firing#

Taiwanese chaishao teaware is made through wood firing, which can leave ash deposits and flame markings on the surface. The term describes a firing practice, not a single clay. Contemporary studio work should be distinguished from the longer history of wood-fired pottery in Taiwan.

Taiwanese rock-mineral clay describes coarse ceramic bodies used by contemporary workshops for teaware. It is a workshop material category rather than one geological clay. Recipes, firing and surface texture vary; yankuang and commercial names such as laoyanni should be read in the context of the particular maker.

The cited 2015 monograph places these materials in contemporary Taiwanese studio teaware. Priority claims about who first formulated a body, exact quarry origins and the equivalence of trade names require independently documented workshop histories.
