Another thing to see the overall effect, whether the Zhou Zheng, with or without deformation, glaze is smooth, whether the strange color. Finally, the optional display of ceramic art of a good place to light during the day, lights are often out of error. Lightly knock on the porcelain can listen to the sound is crisp and loud, there are ceramic cracks husky voice.
Porcelain generally have to buy a "four-character formula" that "look", "listen" and "bi", "test."
"Look" is to closely observe both inside and outside the upper and lower porcelain again. To see whether a glazed porcelain smooth lubrication, without scratches, holes, black spots and bubbles; two to see whether the regular shape, with or without distortion; three to see the picture there is lack of non-destructive; four to see whether the formation of the bottom shall be placed a smooth, non- burr.
"Listen" to listen to lightly knock is the sound of china. If the sound crisp, sweet, then fine porcelain dense, non-dehiscence in high-temperature firing, the porcelain completely. Such as sound dumb, we can conclude that there is dehiscence porcelain, or porcelain is not complete, this type of porcelain by the hot and cold changes, easy to crack.
"Than" is compared. On matching porcelain, to compare the parts, to see whether the shape and coordinated decorative screen. Particular set of exquisite blue and white or blue and white porcelain, blue and white coloring with the sintering temperature because of different changes, so with a blue and white, color depth with a light, a few or even dozens of sets of cold porcelain, such as the various pieces of blue and white coloration were significantly different, this porcelain was much less.
"Trial" is the test covers, test equipment, test. Some of porcelain with a lid, and some porcelain combination of several components, in the selection of porcelain, do not forget about cover the lid again, try assembling the components and see if appropriate. In addition, some porcelain with special features, such as dripping Guanyin, automatically dripping water; Kowloon fair cup of wine, filled up to a certain location, will all light leakage. So what to test to see its functionality.
