“What Do We Know About Coromandel Screens? The Art Historians’ Perspective” (co-authored by Xialing Liu, Lianming Wang)
Regional divergence and the cross-regional distribution of Coromandel screens (kuancai) have perplexed art historians for decades. So far, no definitive criteria have been established to determine where and when these screens were manufactured. Due to the lack of examples with clear references to their production sites and dates, scholars have been unable to establish a developmental sequence. Drawing on a comprehensive survey of Coromandel screens in global museum collections, this paper identifies major sources of imagery and cross-referential features — such as regional carving styles and artistic exchanges among southeastern coastal regions, including the Greater Suzhou region (Huizhou and Yangzhou), southern Fujian, and Guangdong.
The first part of the paper analyzes the screens’ central imagery, while the latter part examines shared characteristics and the origins of frames produced in different regions. Central to the discussion is a proposed three-tiered corpus of “standard pieces”: (a) screens with clear workshop and production-site attributions, (b) screens bearing inscriptions or birthday essays that provide references to dates and locations, and (c) screens carved in styles demonstrably similar to the first two types yet lacking inscriptions. The second part of the paper elaborates on the frames of the screens. Through a detailed examination of their decorative motifs — (a) Chinese Bogu patterns (hundred antiquities), (b) floral designs, and (c) mythical beasts and animals — it traces the screens’ pictorial sources and their cross-media relationships, particularly with printed illustrations. This approach supports the existence of an “anonymous lacquer workshop.” Consequently, the study of the frames offers a potential methodology for authenticating and defining the “standard pieces” in terms of manufacturing provenance and dating. Building on these discussions, the paper traces the reciprocal exchange among the flourishing commercial painting market, the printing industry, southern kilns, and lacquer workshops along China’s southeastern coast during the late 17th century.

“An 18th-century Chinoiserie Half-cabinet with Panels Made from Coromandel Screens in the Collection of The State Hermitage Museum” (co-authored by Kamilla Kalinina, Marina Michri, Daria Kulikova)
Dr. Kalinina’s presentation will be based on her research collaborated with Marina Michri (Conservator, Department of Scientific Restoration and Conservation) and Daria Kulikova (Junior Researcher and Curator of Furniture, Department of Western European Applied Art) from the State Hermitage Museum, Russia. Their subject of research is the history of a chinoiserie half-cabinet in the Museum’s collection that is decorated with ormolu and colourful panels, as well as the results of investigation of the composition of the materials employed in creating the lacquered surfaces. The panels feature polychrome carving on a black ground with a variety of subject matter: palace roofs in the clouds and a procession of warriors on the front, flowers and birds on the sides. This piece of furniture was previously in the collection of the princely Yusupov family. Identification of the French marks confirmed that the cabinet was made by 18th-century French craftsmen using Coromandel screens imported from China. The article presents an analysis of the decorative materials used to create the panels in China and gives an example of the integration of Coromandel screens into European palatial interiors in the form of furniture in the chinoiserie style.
The following methods were used to study the stratigraphy and composition of the non-organic materials in the lacquer coating: polarized light microscopy (PLM), scanning electron microscopy in combination with energy dispersive X-ray analysis, (SEM/EDX). Pyrolytic gas chromatography and mass-spectrometry with thermally assisted hydrolysis and methylation (THM-Py-GC/MS) were employed to determine the composition of the organic materials. The analysis revealed such biomarkers in the lacquer as a heptadecylcatechol in the methylated form 1,2-dimethoxy-3-heptadecylbenzene and the acidic catechol C10 – arlenic acid in the methylated form 10-(2,3-dimethoxyphenyl) decanoate. A number of biomarkers for cedarwood oil were also found in the aforementioned background layer. The restoration materials on the surface of the panels were identified as a coniferous resin and sandarac.

“Chinese Lacquer in Portuguese Collections: Material Study of Three Kuancai Screens.” (co-authored by Maria João Petisca, Catherine Matsen, Huixin Li)
Dr. Petisca’s presentation is based on her research paper with the same title co-authored with Catherine MATSEN, Senior Scientist of Scientific Research and Analysis Laboratory, Winterthur Museum, Garden and Library/ Affiliated Associate Professor, The Winterthur/University of Delaware Program in Art Conservation, and Huixin LI, Curatorial Track Art History PhD Student, University of Delaware/ Graduate Assistant, Winterthur Museum, Garden and Library. This study focuses on the materiality of three kuancai (engraved polychrome) screens. Two of the screens (FMA305 and FMA5279) belong to the collection of the Museu Medeiros e Almeida (MMA) in Lisbon and are attributed to the 17th century and the 18th century. The third screen belongs to the collection of Jorge Welsh Works of Art and is attributed to the Kangxi period (1662-1722). Screens produced in the kuancai technique, or the so-called Coromandel lacquer, are frequently of considerable size. The three screens analyzed relate due to their reduced height, the highest being 116cm. All screens depict European figures in different activities. Despite their similar size, one of the screens seems to have been cut off from a bigger dimension object and reassembled as a smaller screen. The finish stratigraphy of the three screens was investigated using cross-section microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), and pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS). Results identified the lacquer species used in the manufacture of the screens as well as on the materials present in the ground and pigmented layers. This technical study clarified that one of the MMA screens was most probably once part of a larger screen.
