Ceramics with excellent products and first-class goods is how divided?
It is the best grade, no concept of honorsBut now the general order is the standard of agreement, so to speakIf you are both first-class and superior, superior is better than grade oneBut the general manufacturers will not be so out of order, inappropriateGenerally superior and qualified productsAt this time superior than first class goods, a little better than qualifiedSo one, two of the bar, qualified, basically three class appearance
Of course there are excellent products and first-class goods division, the packaging will be express, a good brand is two stars, and excellent products Chinese characters, and the general brand seems to be three stars, excellent products and a product of the difference in grade one and, often excellent products appear a little flaw in the production process in and into a product packaging, so excellent products and a product price will vary greatly!
At present, the standards for ceramic products are: first-class, first-class, two, two grade, qualified products and so on.But the standards here often change. Because the burning of each ceramic device is difficult. Products that are easy to burn, excellent, first class, are well distributed. Difficult to produce products (easily flawed), the share is not so clear.The best products are not allowed to have spots or blemishes on the ceramic surface,First on the surface of the ceramics is not more than three of small diameter spots, or pores, needle etc..
