Brief note on identification: the exact historical form called "线条水平壶" (literally "lined/horizontal teapot") is not a widely standardized name in the published corpus of Chinese teapot types, so the identification is ambiguous without further provenance or an image. Below is a safe, general description and context based on the name.

Description (English, ~150 words)
The name 线条水平壶 suggests a teapot whose design emphasizes horizontal lines and a pronounced lateral or low-profile silhouette. In Chinese ceramic and teapot traditions, form names often describe either decorative motif (线条 — linear/striped decoration) or the overall axis and proportion (水平 — horizontal/flat). Such pieces tend to present a broad, elongated body with stacked or incised bands and a restrained, geometric aesthetic.

Historical context
Chinese teapot design developed over centuries from utilitarian wares in the Ming and Qing eras to specialist forms (notably Yixing clay and Jingdezhen porcelain) prized for both function and artistry. Horizontal, low-profile and linear treatments are characteristic of later refinements where emphasis shifted to silhouette, surface rhythm and balance. Without specific makers’ marks or material information, this description remains general: the form likely reflects that ongoing Chinese tradition of marrying functional brewing needs with clean, architectonic decoration.
