Data for: Color-Forming Mechanisms and Manufacturing Techniques of Qianlong-Period Famille-Rose Architectural Tiles from Yuanmingyuan
Description
Abstract/Overview: This dataset comprises the primary analytical data supporting the research article titled "Color-Forming Mechanisms and Manufacturing Techniques of Qianlong-Period Famille-Rose Architectural Tiles from Yuanmingyuan". The data focuses on the chemical composition and microstructural characterization of famille-rose (fencai) architectural tiles excavated from the Ruyuan site (Garden of Likeness) in Yuanmingyuan Park, Beijing, dating to the Qianlong period (c. 1765–1767). Methods and Data Acquisition: The dataset was generated using the following analytical techniques: LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry): Used to determine the major oxides and trace element concentrations (including Co, Mn, As, Pb, Au, Sn, etc.) of various colored enamels (dark blue, light blue, pink, green, yellow, white) and the base glaze. SEM-EDS (Scanning Electron Microscopy with Energy Dispersive Spectroscopy): Used to analyze the microstructure, layer stratification, and particulate inclusions (e.g., gold nanoparticles, lead-tin oxide particles). Optical Microscopy (OM): Used for characterizing the glaze cross-sections and surface morphology. File Inventory: Figure Contains the quantitative chemical composition data derived from LA-ICP-MS analysis. The sheet includes data for: Cobalt-blue pigments (smalt/domestic ore mixtures). Gold-based pink enamels (colloidal gold). Lead-based green and yellow enamels. Arsenic-based white opacifiers. Table.docx: Contains high-resolution SEM Back-Scattered Electron (BSE) images and Optical Micrographs showing the glaze stratigraphy (body, base glaze, white ground, and colored enamel layers). Significance: These data provide quantitative evidence for the transfer of falangcai technology to architectural ceramics during the Qing dynasty, specifically highlighting the use of imported European smalt, the application of "glass white" (arsenic opacifier) for color modulation, and the identification of gold nanoparticles in pink enamels.
