作品题材、载体、工艺和逐项材料依据
此前：此前未列此项。
现在：{ "classification": { "subject": { "key": "buddha", "label": "佛像", "sourceValue": "Thangka with Buddha", "sourceField": "Title（馆方题名）", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823" }, "support": { "key": "cloth", "label": "布（具体纤维未知）", "sourceValue": "Distemper on cloth", "sourceField": "Medium（馆方材质记录）", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823" }, "technique": { "key": "painting", "label": "绘画（具体工序未知）", "sourceValue": "Paintings；Distemper on cloth", "sourceField": "Classification / Medium（馆方分类/材质记录）", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823" } }, "materials": [ { "topic": "载体", "value": "馆方用词为cloth，本站归为布；未据此确定棉、麻、丝等纤维。", "evidenceType": "museum-record", "sourceField": "Medium：Distemper on cloth", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823", "boundary": "这是馆方公开记录，不是本站取得的纤维检测结论。" }, { "topic": "绘画材料与工艺用词", "value": "保留馆方原词Distemper；馆方Classification为Paintings，本站仅归入广义绘画。", "evidenceType": "museum-record", "sourceField": "Medium / Classification", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823", "boundary": "不据此推断具体颜料、胶结料、底层配方、笔法或制作步骤。" }, { "topic": "具体颜料与胶结料", "value": "未知：当前所核公开记录未列逐项成分和对应分析报告。", "evidenceType": "not-published", "sourceField": "本次所核公开馆藏记录", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823", "boundary": "未列不表示没有使用，也不表示馆方没有检测；本站未取得可引用的逐项检测依据。" }, { "topic": "布的具体纤维", "value": "未知：当前所核公开记录未列纤维种类及分析依据。", "evidenceType": "not-published", "sourceField": "本次所核公开馆藏记录", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823", "boundary": "不能从图像纹理或cloth一词判断丝、棉或麻。" }, { "topic": "金箔或其他金属成分", "value": "未知：当前所核公开记录未列相应成分分析。", "evidenceType": "not-published", "sourceField": "本次所核公开馆藏记录", "sourceURL": "https://www.metmuseum.org/art/collection/search/37823", "boundary": "不能把画面中的金色或亮度当作金箔/金属含量证明。" } ], "limits": [ "题材、载体、制作工艺是三种不同信息；本站规范词用于当前四件馆藏的同口径查找，不判定画派、仪轨适用或作者资格。", "馆方记录与分析检测是不同证据类型。下列未知只描述本次所核公开页的披露范围，不能写成“馆方未检测”。核对日期：2026年11月2日。", "本站尚未收录这件作品的背面照片、逐项材料分析或实物状况检查报告；这不表示馆方没有这些资料。当前馆藏不是本站在售商品。" ] }
依据与原因：从对应馆方题名、Medium与Classification分列；馆方记录不是材料检测，未公布的成分与纤维继续未知。
