采用X射线荧光能谱仪、分光光度计、X射线吸收精细结构等测试技术,对不同种类紫砂原料和烧制试片进行分析,以探究原料及烧成温度对紫砂器呈色的影响规律.结果发现:Fe2O3是紫砂器重要的呈色氧化物,其含量的高低、矿物存在形式的不同影响着试片的颜色.不同类型的紫砂试片均有不同的颜色,但所有紫砂器的色度坐标均位于红色和黄色的区域内.其中紫泥类试片红、黄两色的饱和度非常低,绿泥类试片黄色色相非常高,红泥类试片的色相与紫泥类一样,但饱和度非常高.同一紫砂原料在不同温度下烧成的紫砂试片的颜色不同.随着烧成温度的提高,紫砂中铁离子氧化态降低,即赤铁矿高温时易析出磁铁矿,造成紫砂试片颜色的变化.

<正>清初,以摹古、崇古为宗旨的"四王"绘画风格以笔法遒美、墨韵高古、气格清隽、士气盎然得到了清皇室的扶植,他们讲究师承和笔墨技法出处,传承着元代文人山水画的审美标准,追求笔墨情趣的高逸脱俗。其中以太仓地域为主的王时敏、王鉴、王原祁在绘画风格与艺术思想上,均

This paper makes a textual research of Wanghui’s acquaintances on his learning tour across the country covering his visiting the famous historic and cultural sites, learning from the distinguished masters and edging himself into the upper class. In his early life he was wandering about the areas of Changshu, Taicang, Wuxi, Suzhou, Hangzhou and Jinling, etc. to acknowledge Wang Jian, Wang Shimin, Qian Qianyi as his teachers, make friends with Tang Yuzhao who was a collector from the southern region of the Yangtze River, Yun Shouping who was an adherent painter, and learn by copying a lot of traditional works by the famous artists. The mid-aged Wang Hui lived with the officials and merchants by exchanging views with them on calligraphy and paintings until he went up to Beijing to participate in painting Kangxi’s Inspection to the South (Kangxi Nan Xun Tu) as the major creator of the great work, during which he got to know the new imperial noblemen and Song Junye who later became his student, Wang Shan, Wang Bian who were Wang Shimin’s sons and Wang Yuanqi who was Wang Shimin’s grandson. His experience plays a critical role in improving his living condition, promoting his social status and reaching his artistic attainment.
