Overview

This magnificent 37cm blue-and-white porcelain basin features a central roundel depicting a ethereal misty landscape with pavilions set against mountain peaks. The exterior is boldly painted in cobalt blue underglaze with scrolling floral peonies, complemented by a geometric cell-pattern rim border and classic plantain-leaf bands near the high foot ring.

Story

Crafted in the famed kilns of Arita during the Edo period, massive porcelain bowls like this were created for grand banquets and formal ceremonial gatherings. The cobalt blue glaze was applied freehand before firing at extreme temperatures, fusing the design permanently into the porcelain body.

Maker / Origin

The potters of the Arita region perfected porcelain production in Japan after kaolin clay was discovered in Izumiyama in 1616. Kilns produced 'Sometsuke' (underglaze cobalt blue) wares using techniques heavily influenced by Chinese Ming and Qing dynasty imports, yet developed a distinctly expressive, painterly Japanese aesthetic.

Condition & Value

The bowl shows scattered kiln specks (iron spots/pinholes) from firing, typical of antique hand-made porcelain. Minor wear to the unglazed foot ring, with no major visible structural cracks or large chips in photos, though close inspection for hairlines is recommended.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
