Overview

This exquisite set of six oval porcelain dishes showcases a striking diagonal composition, split between a soft celadon glaze and a hand-painted underglaze blue cobalt landscape. The technical mastery required to execute a sharp, clean division between two distinct glaze compositions on porcelain was a signature achievement of late Edo Imari kilns.

Story

Eighteenth-century Arita potters perfected this split-glaze technique, combining calm sea-green celadon with detailed cobalt landscapes. Having a complete set of six surviving in such remarkable condition is a real historical treat.

Maker / Origin

Made in the famed kilns surrounding Arita in Hizen Province, these pieces represent the collaborative effort of master throwers, painters, and glaze specialists working within the Imari tradition. While individual artisans rarely signed their everyday tablewares, the 'Fuku' (good fortune) mark on the base signifies high craftsmanship meant for refined Japanese banquets.

Condition & Value

The set appears to be in remarkably good condition with strong glaze clarity and vivid cobalt blue underglaze paint. No major chips or structural cracks are visible in the photos. Excellent overall preservation for Edo-period tablewares.

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
