Of work of a Na Gong be born, its process is far want than what you imagine complex, from exploitation, choose expect sculpture, want to make outstanding work through ability of layer upon layer test.
Na Gongdiao after all by what small expensive, have the following reason:
1, exploitation is difficult
Because the quickness of Na Gong price is climbed,rise, the interest is driven under illicit the phenomenon that digs excessive to collect is serious. From exploitation up to now, upper ore already picking up dangers, extract to continue Na Gong ore, can to deeper local excavate, the ground is made by gouge many greatly small pit, some has been as deep as ten meters. Even so, red mine makings also is to short with each passing day south, good stuff is little little.
2, crackle is much
Na Gong's faultiest place, crack more namely. Na Gong expects crackle is very much, it is the sort of big be well versed in is cracked even, and the color inside Na Gong makings also is met as crack and change. Seem to hold out perfect material for making clothes it seems that, if careful observation can discover, flawless without one place. High grade Na Gong makings is very accordingly exiguous, can carve the good material that use truly very few.
3, foreign matter is much
Na Gong goes in in mix into of the meeting in the process that fashion of a few other mineral, because this appeared,the miscellaneous splash with color differ depth is nodded or spot piece, namely foreign matter. Na Gongzhong's impurity is the markeddest flaw, especially a big the sort of, reduced Na Gong's quality directly. If be the stain of a few, return the pen that can become bit of eyeball probably.
4, technology is high
Because Na Gong's color is onefold, give priority to with red, it is more difficult to choose on sculpture subject matter accordingly, and taller also to carver requirement, otherwise very inaccessible faster sculpture artistic concept. The Yu Nagong of sculpture, be just as spice taste at dish, not the Na Gong of classics carve although aesthetic, but the change that lacks artistic conception. The level of carver, also decided the level of Na Gong work.
