How is the quality of ceramics assessed?
Ceramics, of course, first look at the need. If you are an ordinary household, the average person likes to be thick, but I tell you, the thick ceramic is made of ordinary porcelain mud. The process is more general. The family is still living. A little better, mainly in high white porcelain. The thick black partial (mainly white head), if the high-end, so is the Royal Porcelain, Bone China, porcelain, jade, these are the fine transparent primarily, porcelain is fine, so it is in fine ceramics.
Quality assessment requires a standard, which involves many aspects of construction ceramics. Mainly to see your use, general construction ceramics are imitation of natural stone. So compare the physical parameters of the natural stone you want to imitate with the building ceramics you need. The physical parameters of the natural stone are better than those of the natural stone. General physical parameters such as hardness, wear resistance, weather resistance, gloss, water absorption, acid resistance, alkali resistance, etc...
The second is for gifts, gifts with the general choice of fine ceramics, so that ceramic exquisite workmanship, such as imperial concubine porcelain, porcelain delicate, white whole body, good light transmission. Particularly high ornamental. Also, choose flowers that are exquisite and not too rough. Why?. Because the flower surface is too thick, if you use nail button down, then this will be thrown. If the surface is smooth, slightly better feel, as if in touch grandpa Mao's head like. This is good, slightly concave and convex.Well, in general, pick ceramic ah, we have three steps:The first step is to look at what it looks like, look at the color, the ceramic to be white, the body without black spots, cracks, and so on. It depends on whether the design is harmonious and exquisite, whether it is light and transparent, whether the lines are neat and exquisite.The second step to touch: to feel with your hands. Is the edge of the body smooth?. Is it too bumpy?. Or is the flower surface too rough?. Also, such as bowls, that is, the soles of the feet is too rough or too slippery, too coarse, there is no fine grinding. It's too slippery. It's not safe. The table may slip off (especially with water and the desk is not normal)The third step: to put the bowl or cup, placed in the flat palm, beat with stingy things. The voice is crisp and melodious. It's a fine porcelain.
