One paw, two look, three listen to the four lifting
One paw: refers to the weight in the hand, to see whether its weight is moderate; at the same time, the hand can be used to feel the porcelain of the fineness and hardness. The addition of calf bone powder makes the weight of bone china will be lighter than other types of porcelain, thickness than the general porcelain thin, the finished product is light, dense and hard (twice as much as daily porcelain), not easy to rupture.
Two look: is to look at its surface, good bone china color is natural bone meal unique natural milky white, glaze such as a mirror, high gloss, white as grease, moist as jade feeling, the picture is exquisite, bright colors;
Three listen: is to hit with a hard object, the listener whether there is a golden yellow stone crisp sound; with the forefinger and thumb gently a bullet, you can hear bone china! "Ding" a crisp sound. If the hand dipped in water in the bowl mouth friction, will also sound like an airplane flying over the roar.
Four lift: is the porcelain to the light source or cover on the light bulb, against the bright light to observe the permeability of bone china, good bone china should be better light transmission and uniformity without impurities.
Production process:
First of all, Yazhi crushed completely refined porcelain clay and natural bone powder, through the soil engineering high temperature exercise, and then through the cutting-edge molding project, the transition to plastic engineering. In the state-of-the-art RHK, the object is molded once at a high temperature of 1,280 degrees Celsius, and then goes through the vibration grinder to smooth the surface. After the grinding and selection process for inspection of defects, the enameling process is followed by the glazing process with the spraying of paint buttons. The glazed ware is then subjected to a high temperature of 1130-1150 degrees Celsius and 18 hours of secondary molding of the glaze. After the second molding of the ware, it passes through 2 times of the selection process, and after the 3 times of the molding process at a high temperature of 850 degrees and about 5 hours, and the 4 times of the molding process at 830 degrees and 100 minutes, it carries out the 3 times of the selection process for checking the final product, and in this way, the product that has been made through nearly 10 projects is the product of HAENGNAM.
