Methods of counterfeiting black glaze wares from Jian Kiln and corresponding identification methods ②

Methods of counterfeiting Jian Kiln black glaze wares and corresponding identification methods ② The previous article talked about the first type of counterfeiting of Jian Kiln black glaze wares: the whole vessel is new. I believe that all collectors should be more or less familiar with it. So in this article, the author will tell you about the second type of counterfeit work of Jian Kiln black glaze: some are new or remade using old tools.
There are mainly the following situations
① Use the form of bottom connection, and use the old cup bottom unearthed from the kiln site to make a fake
The bottom connection is divided into two types: hot connection and cold connection. Hot connection is The blank is directly formed on the old base and fired in the kiln as a whole. The cold joint uses new fired utensils to connect the old base and make it old.
If it is a cold connection, chemical adhesive is used to directly connect the old base under the newly fired utensils. There are three forms of horizontal connection, vertical connection and circle connection. The first two connection methods are more common and originated in the In the early days, you only need to carefully observe the surrounding parts of the ring foot, or use a metal tool to carefully scrape it, and it is not difficult to find the wiring location. In addition, if you do technical inspection, you can find obvious traces of organic residues. The ring connection method has appeared in recent years, requiring the use of precision. Mechanical tool processing is more expensive. Because the wiring part is very small and precise, it is very deceptive and must be observed carefully to detect it.
Forgery by cold connection cannot be solved by thermoluminescence test.
If it is a hot connection, it is difficult to detect because the glaze water covers the wiring part. However, it can be cracked by combining the analysis methods in Section 1. At the same time, it can also be cracked by using the thermoluminescence test method. The most effective method has a success rate of over %.
② Use the raw-fired vessels unearthed from the kiln site and re-fire them as fakes
Use the raw-fired utensils unearthed from the kiln site, choose those with thick glaze layer and thick carcass, place them in the kiln and re-fire them, and they can be fired Various types of rabbit filaments, solid colors and other utensils are produced. For this type of identification, you only need to observe the glaze surface. The glaze water is tender and the fire temperature is high. The glaze surface is molten and completely vitrified. Most of the glaze is mirror-like. The clearer the sound of the bullet is, the more fake it is. If the original damaged utensils are refired, the original damaged parts can be carefully observed. If there is secondary sintering, it can be judged as refired.
Re-firing the partridge-spotted lamps from the kiln site, either raw or over-fired until the spots fell off, has been done in recent years.
However, because the newly added partridge spots cannot be cured alone, they are cured with glaze, which should be easy to distinguish.
③. Use ordinary utensils unearthed and engraved with various inscriptions to make them fake
Select the utensils unearthed from the kiln site that are in good condition but have no inscriptions, and then add various inscriptions. The most common ones are imperial utensils, mainly for imperial use. Occasionally, there are other auspicious inscriptions and commemorative inscriptions. These post-engraved models are all artificially distressed. Some simple counterfeiters use mud and acid etching to make them distressed, while more sophisticated ones use artificial blowtorches to oxidize and distress them. The former can be cracked by simply observing the oxidation of the carcass at the bottom of the groove and the outside of the groove, while the latter can be cracked by carefully observing the cracks at the edge of the groove and distinguishing between high-speed tools and bamboo knives.
Post-printed models are relatively rare. Because they are different from the original processing methods, it is difficult to achieve the effect of simulation and are rarely used by counterfeiters. Even if they appear, they are easy to identify.
④ Restoration of residual utensils
Mainly involves selecting various types of sticky saggers unearthed from the kiln site. After grinding off the adhesion, repair the grinding part and make it old. Some also add silver or copper inlays behind the rim. The mouth should be covered by grinding off part of the mouth, and there is still part where the pad cake is stuck, just grind off the pad cake.
If the rim is repaired, carefully observe the glaze water under the rim and the glaze water inside the vessel. Under a magnifying glass, you can see the obvious connecting part. If there is a disconnection, it must be repaired or scraped with metal tools. If the sound is dull, it is There is fraud.
If the buckle mouth is inlaid with silver and made old, use a knife to gently scrape the silver buckle mouth part. If there are clear scratches, it will be fake. If the flakes fall off, the fake pad will be stuck and rubbed off. This will not affect its appearance. Acceptable. If the remaining parts are repaired using cold joints, thermoluminescence detection cannot be used to identify them.
