Author: Huang Qiushi | Founder of AI YOU (Ai U) BrandThis paper presents an authentic, fully intact heirloom Longquan celadon lotus-pattern lid box, produced at the Daya core kiln from the Southern Song to Early Yuan dynasty.As a high-grade literati stationery artifact, it adopts classic thin-body and thick-glaze technology, with rigorous hand trimming, precise mother-child mouth structure, and elegant and restrained official aesthetic style.Measured physical parameters
- Mouth diameter: 6.43 cm
- Overall height: 2.56 cm
- Average wall thickness: 0.28 cm
- Weight: 86.5 g
- Body density: 2.61 g/cm³
Core objective evidence
- Extremely rare lost technology:full-glaze firing with fine sand suspension. This high-standard firing process was only popular in the Southern Song to Early Yuan period and completely lost after the middle Yuan dynasty.
- 200× microscopic detection:natural iron-titanium mineral inclusions of ancient raw ore, uniform and dense glaze layer, no modern grinding, acid corrosion or artificial aging traces.
- Transmittance feature:warm orange-yellow body light, which perfectly conforms to the classic porcelain stone + purple gold soil formula of Southern Song Longquan Daya Kiln.
- Global comparative retrieval:No identical or highly similar products have been found in major museum collections, archaeological reports, auction archives and academic monographs. It is a well-deserved worldwide solitary relic.
Academic conclusionThis celadon box is completely consistent with the kiln technology, glaze system, molding and decoration style of the Southern Song to Early Yuan Longquan Kiln system. It can completely rule out modern counterfeits, later imitations and exotic kiln products.This research relies on complete physical evidence to fill the important academic blank in the research of high-grade refined porcelain and lost high-level firing technology of Longquan Kiln in the Southern Song to Early Yuan transition period, and further improves the historical pedigree of Longquan celadon craftsmanship.
