Two pieces of information revealed by the blue-and-white porcelain of the Tang Dynasty (below)

This is a large-scale Tang Qing flower (pictured above),25 cm in diameter, 3.6 cm high, flat, curved wall, turn over the edge, the shape is dignified and heavy, comfortable and generous.The outside bottom of the market did not apply make-up soil and no glaze tire, the quality of the rough loose, the tread has an opening bubble, white in the yellow, and there are light soot marks and brown-red granular pad burn point.Similarly, due to the loose quality of the fetus and low firing temperature (sub-high temperature), tapping with the hand, the sound slightly dull.The glaze color of the market is pale cream yellow, oil-moist bright, although after a thousand years, its still in the light.Under the magnifying glass observation, this large plate of glaze is covered with fine-grained open pieces, in which there is a trace of soil immersion, facing the light side, there are many irregular star-like soil erosion marks on the glaze surface.However, compared with the blue-and-white pot mentioned above, the soil erosion marks on the large plate are relatively light, indicating that the large plate buried in the underground environment is better, most likely unearthed in the uncollapsed tomb of the Tang Dynasty.The large-scale blue-and-white decoration and the above-mentioned blue-and-white pot decoration basic similar, are points, stripes, blue-and-black hair.Because the glaze is bright and thin, the blue-and-white pattern is painted on the thick make-up soil, the green material can not penetrate into the fetal bone even though it is completely melted at high temperature, and the touch by hand, the blue-and-white pattern is slightly convex.
Surprisingly, the blue-and-white glaze has starry, lighter, different clam light.How the five-colored clam light came into being has been mixed in the Tibetan world.However, this strange phenomenon appeared on the white porcelain glaze of Tang Dynasty’s Gongxian kiln, which is a problem that needs to be further studied in the study of Tang Dynasty’s blue and white porcelain.
The author thinks that the clam light on the blue-and-white porcelain in Tang Dynasty is actually the thin-film interference phenomenon of the light in modern physics.It is common to say that the glaze of porcelain must have a solid transparent film formed for some reason.With a high magnifying glass to the light side of the large plate of glaze appeared clam light, it can be found that there is a very thin layer of transparent film on the glaze.Due to the interference of the superposition effect of light reflected on the surface and inside of the film, the colorful clam light can be seen in people’s eyes at different angles.However, due to the uneven thickness of the film and the degree of soil erosion on the glaze surface, we can see the clam light on the glaze surface of the blue-and-white porcelain in the Tang Dynasty.As for the mechanism of transparent film on Tang Qing-hua glaze, it is really a very complicated problem.The mystery remains to be solved by professional scientists and technicians who are interested in the study of blue-and-white porcelain in the Tang Dynasty.
The collection of the Tang dynasty blue and white flowers has turned over a large plate, enough to rival the three Tang dynasty blue and white plates salvaged from the Indonesian sunken ship Blackstone (pictured above).But from the shape of the plate, the form of the foot and the blue-and-white decoration, the Indonesian sunken style and the blue-and-white decoration, the three blue-and-white plates on the Indonesian sunken ship should be burned in the late Tang Dynasty, its decorative features with strong Western Asian style, belongs to the Tang Dynasty trade porcelain.The author’s collection of this large-scale fired earlier, should be the mid-Tang Dynasty products.This complete Tang Dynasty blue-and-white plate, the Yangzhou Museum in China has a backflow of Kenhua small plate.Therefore, the author’s collection of this Tang Qinghua turn over the market and above-mentioned blue and white pot are rare rare treasures.
The article “two pieces of Qing-hua porcelain in the Tang Dynasty revealed information (below)” from the December 2009 “Collection Express” the second phase, the author of Ms. Mu Yanlan, for Juren Hall hostess.
