Methods and skills of identifying antiques How to identify antiques?

1, the shell is full of pulp. When experts identify antiques, they often say that there is no patina. If there is, it is initially confirmed as an antique, if not, it is considered as an imitation. Looking at the shell and patina of antiques is an important method and means to identify the authenticity of antiques. On this issue, many people don't know that the actual patina of epithelial shell describes the oxidative aging phenomenon of antique surface. All kinds of antique appraisal have an evolutionary process from new to old. For example, after porcelain is fired, its glaze will have a strong sense of glaze light, which is usually called thief light. Judging from its light sensing effect, it can be preliminarily considered as a new product. However, after a hundred years of experience, porcelain has been exposed to oxidative radiation in the air and manual scrubbing; The influence of various environmental factors, such as playing and moving, will gradually make the glaze of porcelain old and dark, which is called patina.

2. Comparison of collections. Compare, don't compare, disagree. Ancient and modern, Chinese and foreign, cultural relics are identified by comparative methods. Taking the cultural relics in the collection as an example, when identifying the cultural relics whose authenticity and value are not identified, it is necessary to select the standard instruments of similar cultural relics whose authenticity and age are known, make a comparative analysis, find out the similarities and differences between the unidentified cultural relics and the standard instruments in terms of shape, texture, pattern and technology, and analyze their contradictions and relations. After systematic analysis and research, make a scientific judgment.

3. Modern scientific detection and identification methods. At present, the nondestructive appraisal of ancient ceramics in China mainly focuses on ceramic embryo, glaze composition, firing temperature, firing time and micro-junction. Structure, etc. It is mainly quantified by synchrotron radiation X-ray fluorescence, PIXE and X-ray fluorescence, thermoluminescence and XRF. Analysis and other methods. The use of these methods needs the support of specimen database and a set of advanced equipment.
