Subject:Re: calcification and oxidation in jade
Posted By: LEE Fri, Mar 05, 2010 Hi John, These pieces are obvious fakes, that Anita, and co often associate ever thing, including authentic pieces with. To someone with experience handling authentic jade they are not worth a second look. They have fake written all over them. 1) electric drill marks as you have shown 2) fake calcification with the wrong appearance, these looks frosty and corroded, not smooth and infused. The cup has a thin layer of brown colored cement or line stuck on it. I suspect you can remove that with some acetic acid. If it doesn't come off it is probably a rubber organic base material in which case a solvent like acetone or chloroform might be more successful. Make sure you follow the manufacturer's direction and care when handling such corrosive and harmful chemicals. 3) the material is bad quality and ugly, the ancients do not carve nice things out off any odd rock. These pieces may bot even be made from nephrite they may be made from a rock called serpentine, a relative of asbestos, which is softer and scratchable and reacts with weaker acids like phosphoric acid. I would be a little careful scratching them 4) The design is entirely wrong. I have even seen pieces carved with courting couples. To someone experience such pieces are not worth pondering about. They are cheap tourist junk. |

Posted By: Samuel Mon, Mar 08, 2010 Mr.Lee why you have to attack Anita Mui at any time you have chance to post, it would be nice to talk about jade, and leave her alone. I feel uncomfortable that you do harm to person who spend so much time to make this forum interesting, and we felt that she help us a lot, but you just tried to push yourself to be an expert with no prove of any kind, but word from you. |

Posted By: LEE Tue, Mar 09, 2010 Hi Samuel, she attacked me first and gave her unqualified negative comments about my authentic jade pieces, so I gave her back some of her own medicine . Coming from Northern mainland ancestory I am a little fiery, as expected, but I mean well. I was just trying to help the audience to identify and date jade pieces. I have vast experience in Chinese art and would like to help folks that wants to learn, but she just keep giving her unqualified and unsubstantiated criticism. However I do acknowledge that she has helped educate the audience about the abundance of fakes in the antique jade world. Much are easy to distinguish( e.g John's Chimera and cup or Anita's water dragon) but some are made so well that even an expert will fail to distinguish. the latter are the ones that I am most concern about. |

Posted By: Samuel Tue, Mar 09, 2010 I do not see anything wrong to call her dragon authentic. It fits Han craftsmanship and material. You may look carefully with knowledge of ancient Chinese jade art. And Qing jade from auction house you bought thing from do not have it all. You will have very much trouble when you see 2nd piece like what you bought from auction house selling in China Town for less than a hundred. I remember that the AURORA Art Museum Taiwan Collection has yellowish green Hongshan figurines in their highlight collection that one was purchased in HK for millions, you know whom Aurora bought from? |

Posted By: LEE Thu, Mar 11, 2010 Samuel, this is no way on earth that the dog looking dragon is Han dynasty. The material is wrong first of all, it is too translucent to be native Hetian jade, where is that whitish specks that looks like rice porridge in the material .2) there is no patina that fits a Han dynasty piece, where is that calcification and natural staining, all it has is artificial brown stain, the type you find in china town fakes.3 ) the piece is too smooth to be Han, it has a glossy polish like the one on my modern jade bracelet. 4) what sort of provenance has it got ? What sort of collection did it come from? Has it been seen by a specialist from a reputable auction house? 5) Finally the shape is wrong. I have never seen a dragon with ears that long or a tail that curls between it's back legs. Show me a similar piece at a chinese museum or Taipei or at Sothebys or Christies and i rest my case. Well I am very surprise you can't tell it is fake. I hope you guys aren't concocting your own brand of fake jade, there is already too much of that stuff on the market, to make a buck. |

Posted By: Maertge Fri, Mar 12, 2010 Glossy polish surface (gem luster)is typical of Han jade and this glossy surface was done again in the Northern Song Dynasty and Emperor Qianglong's imperial workshop of the Qing Dynasty. But your goose mirror, the surface look glossy polish, and the craftsmanship are different from Yuan work, it's a modern replica. |

Posted By: LEE Mon, Mar 15, 2010 Sorry not convince. Also the piece on the from the cover of 2008 antique is fake look at the artificial brown russet stain and the shape of that dragon head. All I can say is if the face and eyes of the creature is wrong it is fake- eg wrong eyebrow or wrong eye shape or head size. The head is so small relative to the body it looks like a queen termite. Sorry fake. This are just nonsensical pieces with no museum pieces to back them. Han dynasty dragon that Tommy show is authentic and the shape similar to other bronze examples. It also has a good patina and the shape of that dragon is right with no tail curling between back legs or 2 set of ears like that water dragon, one long and one short. |

Posted By: LEE Tue, Mar 16, 2010 90% of jade pieces that have been buried for several hundred years, would have some sort of surface alteration or patina. The amount of patination would depend on rainfall. the more humid areas will have more patina. The sort of patina will depend on the minerals in the soil. Russet patina if the ground if high in iron oxide. Black patina if the ground is high in organic material and whitish patina if the area is high in calcium. |

Subject:Re: Hetian Jade
Posted By: LEE Tue, Mar 16, 2010 Samuel stop picking on Bill at least at least it has been a learning curve for him and he is willing to further his knowledge on Jade with a open mind. While you keep trying to invent reasons to authenticate your fake jade without any professional guidance. If it is fake it is fake , no matter how many reasons you try to give, it is still fake. Experts at international auction houses are trained and studied and they learn most their authentication techniques by studying and handling authentic museum pieces or pieces from good collections. Most do work closely with curators from museums and other experts. You can take a Asian art course sometimes offered by them. Anyway good luck Samuel with your own style of research but a jade piece is only worth what it can sell at auction and if the auction house refuse to accept it for sell, it is worth nothing. May be ebay. |

Subject:not at all
Posted By: Wah Wed, Mar 17, 2010 Experts from auction house do not allowed to touch artifacts in China Museums, possibly never. International Auction Houses experts are not trained from China Cultural Relic Bureau, no way they have a fortune to touch the real things, but only thing they learn from pictures, books and through thing from collectors and alleged art in museums outside China that they think those things are real. |

Posted By: LEE Mon, Mar 15, 2010 Tommy, all the pieces of jade you show above are Ching dynasty and Hetian, They are milky and more opaque. Shine a bright light through next time there is a major auction and you will see some sort of rice pudding. Do it. |

Subject:Re: Han dragon
Posted By: Tommy Tue, Mar 16, 2010 They are from major auction house where you bought your neo bangle from. They are best quality Hetain jade with high price estimation. The one with rice pudding is a lower quality with low cost. |

Subject:Re: Han dragon
Posted By: LEE Wed, Mar 17, 2010 Claude, auction houses have a reputation to protect and so they do not want to sell any jade that is visibly fake to it's valued clients. There are various ways to authenticate antique jade but most of these have been copied by fakers lately. You get a whole 10 floor building in Beijing full of fake antique/modern Hetian jade carvings for sell. That is why provenance is important because it tells you that the jade has been collected years ago before such sophisticated fakes become present. These days dubious pieces are sold without date, because the specialist cannot tell for sure if it is old. It is up to the buyer to estimate the age. The best way to be sure that the jade is old is that it has a good provenance, coupled with a fitted 18th or 19th century stand. That way one can be very confident that it is definitely not a sophisticated fake. I do buy jade from trusted dealers else than Christies that can produce old receipts of purchase or provenance. Of course all the points of authentication has to be correct. It is not so hard for someone with a lot of experience to spot a genuine from a fake at a 90% accuracy. Yes one should buy within their means, for sure. Anyway good luck with your collecting. |

Subject:rice porridge in the material
Posted By: Tommy Tue, Mar 16, 2010 Mr.Lee, see museum jade with no patina, no sign of age and no rice porridge in the material. |

Subject:Re: rice porridge in the material
Posted By: LEE Tue, Mar 16, 2010 There are signs of stain inclusion in these even though it is minimal. You will see these more clearly when you closely inspect them. Notice also the minute chipping and iregularites on the edges of these object. which are signs of wear. The majority of buried objects have some form of inclusion or calcification on very close inspection no douth about that. The Yuan dynasty dynasty jade plaque of the dragon may never have been buried. Anita's water dragon appears to have 2 set of ears. one long and one short and pointy. Anatomically that appears to be wrong when to compared with the museum dragon plaque that Tommy's posted. This plaque has a good patina as well compared with Anita's, which has a very long fissure on the natural stone- the color of this fissure has been artificially enhanced with a russet colored dye. This is a common method of faking. Natural patina looks very different and has very different colors and shades of colors combined. Jim has a point fakes made from softer material like Serpentine or Soapstones are easier to patinate an they can sometime look very real but of course it is all man made. |

Posted By: Tommy Wed, Mar 17, 2010 Do they have rice pudding? There are high res pictures and show that they are cleaned and clear, no patina of any kind. The white jade belt buckle is of Ming Dynasty and it was a buried jade, displayed at Shanghai Museum. |

Posted By: LEE Wed, Mar 17, 2010 Samuel,this is a photo of a Han dynasty dragon from the Beijing palace museum. Now tell me how is this similar to Anita's dragon or the 2 million Yuan dragon axe?. 1) can you note the difference in patination or do you need new glasses? 2) Can you tell me how the carving style is different, any broad disc cuts on the rib cage area like Anita's? 3) Any artificial brown staining? 4) Any high gloss polish? 5) Tail curling between the back legs that extend to the front legs? Any 2 set of ear? Tell me are the 2 similar at all? |

Subject:Re: not qualified.
Posted By: wah Wed, Mar 17, 2010 What I understand how you authenticate jade via pictures are:-1)base on what Christy has and few items that you bought from, which in your collection has no Han jade.2)All jades auctioned at state authorized, and state owned Chinese auction houses are fake. 3)All jades sold on the net and on the streets are fake because they are not applied by Christy sale tactic and you who learn from it.4)Jade that Christy has, no matter how odd they look different from collections of excavated jade is acceptable because it is Christies�.5)Ancient jade must have sign of age, no sign of age is a fake.6)90% of ancient jade were buried no matter which dynasties they are from.7)Hetain jade must have rice pudding in it, no rice pudding is not Hetain�s at all.8)Glossy polish is only available in 20th century.9)Garnet used for polishing jade.10)Nothing like museums collection and what Christy has are fake, no matter what the record said that 95% of tombs in China were looted. 11)Christy who was banned from selling cultural relic in China has chance to study collection of Cultural Relic Bureau in Chinese Museums.12)You believe in what Christies said and you don�t believe in China auction house people who may put their life in danger by false authenticate cultural relics for sale through the eyes of Cultural relic Bureau scholars.13)You have no confidence to purchase jade from other source but Christy.14)Christy�s jade authentication is final and there are no any jade experts on top of that. |

Subject:Re: not qualified.
Posted By: LEE Wed, Mar 17, 2010 Hi Wah, there are all sorts of ways to "authenticate" a fake antique. One of the way is to pay a fee to the specialist to write you a certificate to say that the piece is genuine. This was the case of a Yuan jar similar to the one sold by Christies for several million pounds. It was documented by CCTV. the chap brought it to a ceramic specialist paid some money and got him to write a certificate, with a red government stamp, to say that it was Yuan dynasty, even though it was a very good sophisticated fake. Than he took it to a local Chinese auction to sell. A curious passer by informed CCTV as she wondered if it was for real. Anyway it turned out to be fake after a TL test was conducted. |

Subject:Seriously off topic
Posted By: Robert Grady Fri, Mar 19, 2010 How this thread got off the original subject of chemically weathered jades is beyond me. LEE, who the heck cares to read in almost every thread you reply to about how Anita Mui's dragon is fake. By now I don't care if that thing is made of kryptonite or fairy dust. You are just creating chain reactions of posters berating you which seem to necessitate moderation and you are oblivious to it. Enough already. Having almost had my say, what I would like to read more about is how the fakers manage to weather stone(jade?); what chemicals are used; what kind of stone...etc. Mr. LEE can you answer this and get back on topic please. |
