Identifying Chinese PorcelainThe process of identifying Chinese porcelain ... Before the last Chinese dynasty ended the expression of crafts and arts followed mostly tradition and was limited to some degree by imperial guidelines and other factors. One of the latter were possibly the methods with which arts and crafts were taught in Far Eastern societies in ancient times, not allowing for free expression and creativity. Apprentices would rather be copying the works of their master and others than creating their own works. Only from the republic period, after the old ways suffered a decline artistic expression of shapes and decorations became more variegated. A major cause of this possibly being the increased exposure to foreign cultures and arts and crafts. Accordingly, the 20th century ceramics became for many a new era with the innovation of new shapes and decorations. Potters and factories started slowly producing items that differered considerably from the traditional wares, incorporating creative influences from abroad. For identifying the age or period of a piece of Chinese antique porcelain shape and decoration are important points of reference once it is clarified that a piece is a genuine antique. The overall evaluation takes into account the following points:
Shapes Since porcelain was first produced, assumedly in the Song dynasty, its forms were limited to certain shapes. Although shapes may have had some minor variations during different dynasties or reigns, deviations within a single reign or dynasty were usually relatively limited. This is one of the factors which helps us identify Chinese porcelain. The shapes usually remained more or less the same in with kitchen or table wares due to the utilitarian purpose and association with our eating and drinking habits. Decorative items like vases, jars and ceramic containers of all sizes and forms were subjected to more change. When visually identifying Chinese porcelain the Shape is the first thing meeting the eye. A short glance over a vase or jar, for example, often allows an expert of Chinese ceramics to assert or discard the possibility of a Chinese object being antique. Some shapes or curves, like those found in Japanese Sake jars or tea cups, are rare or non-existent in the Chinese ceramics of old. Another example are European plates, which have shapes that are originally foreign to the Chinese ceramics culture. Colors If the shape passes this first step of inspection, the expert will most likely do a short evaluation of the decoration's color(s). Here again, certain colors (dyes) or combinations of these were not available in earlier times, or were out of supply due to trading prohibitions in certain eras. Therefore, the presence of a color or colors that will not fit a specific period of production, will result in an item being classified as a later reproduction or fake. The very earliest porcelain decorations of porcelain were made in blue on white ground. But, even the blue color tone differed depending on whether the blue dye was imported, sourced domestically, or was a mix of both. As imports weren't available at all times, this color itself may also help identification of Chinese antiques. Decoration If the item passes color inspection, then the decoration will probably be scanned for any signs of acceptable or unacceptable styles or patterns. Different painting styles may also give some era-specific hints. Footer Looking at the bottom of an item provides the most relevant indications in view to age and/or approximate time of production. The production process was subject to a continuous improvement over the centuries. The presence or absence of signs or features pointing to certain techniques can be an important means to clarify authenticity of porcelain. Mark If there is a mark, the experienced collector will know if the period of the mark and that of the item itself (the points mentioned above) fit into the same picture. Please see the section on marks. Glaze The glaze provides some hints as to the age, as it was different and evolving over time, and may have been subjected to elements (soil, sea, air). Clay As with the glaze the clay/slip was gradually refined and in the 18th century its quality was at the peak. However, it declined somewhat after that. Some defects therefore may not show in porcelain of the 18th century. Age signs Finally, the whole item is checked for the appropriate age signs. Here again, some points involving the techniques (e.g. kiln firing, etc.) developed over time can be included in the overall evaluation when identifying Chinese porcelain.
