100% In-Situ Pig Dragon Bi – Surface Find
A Marvelous Example of an Authentic Hongshan Culture Wind Polished – Surface Find Pig Dragon Bi
Photo Taken with Canon EOS XSi Using EF 24-70mm f/2.8L USM Lens
This tremendous 100% In-Situ Hongshan Culture (approximately 5,500 – 2,500BCE) Nephrite Jade Pig Dragon Bi is being loaned for this article from a private East Coast Collection, and was originally traded from the Fredericks-McIntire Collection of Tucson, Arizona. On the side in the above view, we find the ‘slickened’ look of a typical wind-polished Paleolithic or Neolithic stone item, and the associated degradation of an article that has been polished by water, wind and particulates for an extended period of time. This is the side that would have been downward-facing the longest during the passage of time, as the design is better preserved than that in the following picture. Also, you may notice an in-situ piece of agate that has been lodged in the mouth of the pig dragon, a technique that is commonly used as a detail in forgery. However, this particular agate sliver has actually become one with the stone through the aging process, as will be shown in the accompanying macro- and microscopic images. Most of the time, these types of stone ‘impregnations’ are accompanied by aliphatic cements or other types of glue, and just ‘pop’ right out using a fine metal pick, leaving the glue residues clearly visible, and easily removed.

In this photo we again see the characteristic wind-polished look that gives an artifact of antiquity such a beautiful sense of timeless durability, such as what we see in the old Acheulean hand axes from Africa and wonderful stone artifacts from other parts of the world where the dry windswept regions, with their occasional rain and slight organic material associations, create these lovely patinas. While these regional and climactic conditions do have more of a tendency to wear away tooling marks, they also leave us with other quite distinctive clues as to the time spent above ground, if one looks closely enough at the artifact to ascertain the approximate climactic environment to which it has been subjected. While this Pig Dragon Bi was most likely a funereal item, as most Hongshan artifacts of religious significance were, it was unearthed for an unknown reason at some point in its early history, and left to weather on the surface for millennia. Pig Dragon Bi’s were of extreme importance to the Hongshan Culture of ancient China, as attested to by the many examples of these burial objects to be found in the archaeological records of tombs of the old Shamanic lords and tribal leaders. But it does lead one to ask the following: how does a sacred nephrite stone that was reserved for the Shamanic elite ONLY, become so prevalent on the Internet today, with literally thousands being offered for sale daily. That question then leads one to doubt very seriously if there could possibly have been hundreds of thousands of Shamanic elite buried during neolithic times. In a lifetime of collecting, we have actually owned only eight authentic Pig Dragon Bi’s, but have seen literally thousands of replications, some with a starting bid as low as one US penny, plus shipping. Every year around the time of the Tucson Gem and Mineral Show, I am subjected to people wanting to show me their ‘treasures’ by the hundreds, and telling me there is no way a person could make one that cheaply. My patent response is that a desperate man will do quite a bit of work for enough rice to keep his daughter fed throughout the winter, so that the family does not have to leave the little one beside the road.

This wonderful side view shows us all the characteristics of a genuine surface-find, wind-blown Hongshan Nephrite Jade. This Pig Dragon Bi was subjected to all of our usual pre-microscopic viewing tests; an extended soaking in acetone (which degrades newer waxes and helps in the removal by power sprayer of the waxes and accompanying dirt deposits used to replicate age), one in bleach (which removes dyes and applied iron filings extremely well, when a piece has had a light acid bath and then dyes and rust applied to make it look old), and a short oxalic acid bath to remove the deeply baked-on ‘shoe polishes, dyes and mud’ that they have begun to use once again (as they did five years ago) because it is not effected by acetone, as non-baked-on newer waxes are. What you see here is a Pig Dragon Bi in its ‘as found’ condition, even after being scrubbed, cleaned and shot with our high-power water spray gun. What remains is what has legitimately adhered to the original nephrite after thousands of years. The dirt, oxidized iron, and manganese deposits you will see in the close up pictures are all now a part of the artifact, as is another anomaly that we have never seen in print before, but will explain as well as we possibly can, in photographs of the Pig Dragon Bi and some that we will use for comparison.

The two photographs above show at higher magnification the soil deposits still adhering to the darker green nephrite which the Hongshan carver chose for this Pig Dragon Bi. The photos also show the nephritic fibers, and how the windblown debris started to pit the softer fibers of the nephrite, leaving the tougher fibers to rise a bit above the surface, exposing them more to wind-polishing. Contemporary artists are well aware of this characteristic of nephrite; when they polish certain types of nephrite jade, the surface often shows these higher and lower areas. This can be used to great benefit when carving a new item. When one wishes to be free of this trait in the end product, however, wax can be used to mask it; alternatively, a type of nephrite like a Wyoming “Edwards Black” can be chosen instead. because the tightness of its grain is such that there is little or no chatoyancy in the stone, as the fibers are so tightly and uniformly compacted. The parts of the photos above that show the green jade starting to turn a whitish color are extremely important here, as they begin to illuminate a property of nephrite that has, to our knowledge, never been discussed, and which departs from the theories of degraded funereal nephrite artifacts (which are well-documented), and the ‘chicken bone’ effect that has never been adequately explained, and which occurs in artifacts all the way from Neolithic jade funereal pieces to Qing Dynasty burial items. We are going to explain our theory on surface-find, degraded green nephrite jade with a whitish rind, by comparing it to the chemically very similar agate, from the quartz family, which occurs simultaneously in one amazing old artifact.

Both photographs above show a degraded sliver of agate that has become fused into the jade mouth of the Hongshan Pig Dragon Bi. The first photograph was taken at 1X with our Macro Lens, and the second at 2X. In both photos we can see the exact same deposits adhering to both the agate and the nephrite of the Pig Dragon Bi. Also, we can see the clearer portion of the agate and the more degraded whitish sections that match the white portions of the nephrite, in both photographs above and in the previous close-ups. In the next photograph, taken at 40x power through the microscope, you will be able to see even more clearly the depth to which the the agate has degraded, and the ‘new’ clearer parts where the degraded agate (being more fracture-prone than nephrite) has chipped off, leaving a newer, ‘fresher’ surface. We believe that this white degradation of both the agate and nephrite occur in arid, wind-blown regions without the necessary moisture to turn the iron deposits in both the agate and the nephrite into the much more familiar red rind of oxidation; rather, we believe it is more a factor of slight water intrusion into the stone, coupled mainly with ultraviolet light, which catalyzes this whitening process we see occurring on both stones simultaneously. Having had the unique opportunity to study, over the course of two-and-a-half years, in excess of a hundred pieces of degraded agate tools from Paleolithic to Neolithic sites, from the collection of Mr. Robert Willingham of Tucson, Arizona, under microscopic conditions, it has afforded me the exceptional experience of seeing all types of exotic lithic agate material in varying stages of degradation. Most of the pieces studied came from the famous Utah Agate Basin Area in which Mr. Willingham grew up and collected, but there have also been outstanding examples from Northern Africa, some dating back as far as 75,000 years or more. Many pieces studied had parts of the original core material left on them, and others had been re-chipped and re-used. Many of them showed evidence of which side of the artifact faced the ground the longest and which side had been more exposed to the harsh elements by facing upwards. We still retain numerous fine ‘study’ examples in our collection, for on-going research.

In this photograph at 40X power, we can clearly see the broken-off degraded piece of agate in the white piece in the center of the picture, and to the right side of the photo we see the surface of the nephrite starting to degrade into the same white coloration. The portion in-between the old degraded agate and degrading nephrite is naturally adhered soil deposits, which have also ‘fused’ the agate to the nephrite on both sides where it got stuck in the crevice which was the mouth of the Pig Dragon Bi, a very long time ago. The portion of the agate to the left of the degraded white section has again started the degradation process, and with time and exposure to ultraviolet light, if left alone and not re-polished, will become whiter, and the degradation will increase in thickness. In the next few pictures, we will show some more examples of this phenomenon on different agates before we resume our microscopic study of the Pig Dragon Bi.

The photograph above shows a fine example of an approximately 75,000 year old North African agate stemmed point. This type is considered among the earliest of the true chipped points, and was most likely a knife or projectile point. Note the heavy degradation to the fractured and crumbling white ‘crust’ on the far right side of the photograph, and the lesser degraded portions in the center and along the wind polished edges. When these heavily degraded areas are subjected to a violent act, such as a good river tumbling after a driving rain, portions are knocked off and the process renews itself. The areas most prone to wind polishing usually take the longest time to degrade, but differing circumstances (like a climactic change or partial burial) will produce differing results over time.

The above photograph is of a 100% In-Situ Neolithic degraded agate ‘tool’. Some ‘re-chipping” can be seen along a few of the leading edges, and appear under microscopic observation to be places where the stone naturally fractured from impact, and were not caused by intentional re-sharpening efforts. In these areas we find remarkable opportunities to study the degrading patinas and re-patination over time. Also evident is which side lay upward, facing the sun for the longest period and which side was face down, as many pieces we studied were verified as to exactly how they were found, how much was covered up, and how much of the item was sticking out of the surrounding soils. This tool was also found in a ‘blow-out’ and has received quite a bit more natural tumbling and cleaning than the Pig Dragon Bi under discussion, or the African agate point above.

This photo at 40X microscopic power is of one of the tiny broken-off pieces on the Neolithic Utah agate tool above, and shows the similarity to the breaks and the colors associated with the agate in the mouth of the Pig Dragon Bi, under identical microscopic conditions. Note: The colors are almost identical, the time frames match in that they are both from approximately the same period, and they are both from approximately the same climactic conditions. Now we shall continue with more on the nephrite Pig Dragon Bi on its own.

Above is a wonderful photograph showing all the above-mentioned attributes of an authentic surface-find, Neolithic nephrite jade, including the whitening effect from the ultraviolet catalyst on the jade surface, the soil that has totally penetrated the porous surface of the nephrite to the point of actually becoming one with the stone, and the effect of the wind polishing to bring out the shine of the nephritic fibers and even the areas of degradation and hardened soil adhesion. No other enhancements or treatments could be found on this artifact, nor any recent polishing marks, even using the microscope up to 90X magnification.

This Manganese crystalline growth in the center of a depression of the Pig Dragon Bi again shows the 100% In-Situ nature of this artifact. Coupled with the dirt encrustation and the whitening of the dark green nephrite, this manganese crystal is just one more important bit of positive proof of extreme age in an incredible piece that has never seen another tool or polishing, other than the one it received from the Master Carver who made it over 5,500 years ago.

The above two photographs offer conclusive proof to us of the above statement that no re-tooling or intentional re-polishing has ever occurred on this surface-find, wind-polished Hongshan Pig Dragon Bi, as the presence of emerging dead tree or grass roots, from such a deep depression in the surface degradation inside the suspension hole, speaks volumes by itself.

This kind of thorough and exacting analysis of an authentic piece substantiated with superb photos is what informs, educates and raises awareness about jade in general and antiques specifically.
Very well done David, and although not everyone will comment, I am sure many really appreciate your hard work and insights to create not one, but a whole series of excellent examinations, the likes of which have never been done before.
Thank you,
