Embodiment 1

[0027] Using a laser Raman probe to detect the hydroxyl group in the glass phase of the ceramic glaze, that is -OH, to identify the authenticity of the sintered ceramics made 50 years ago, and the ceramic glaze glass phase containing hydroxyl groups is 50 years old. Ancient ceramics made by sintering in the past, ceramics that do not contain hydroxyl groups in the glazed glass phase of ceramics, ceramics made by modern sintering are fake ancient ceramics.

[0028] The laser Raman probe, model RAMANOR-U1000, is produced by French J-Y company.

[0029] The principle of adopting the present invention to identify ancient pottery before 50 years is as follows:

[0030] The water absorbed in the ancient ceramic glaze 50 years ago is discharged at 100-110°C during the sintering process; the water brought in by other mineral impurities in the ancient ceramic glaze 50 years ago is discharged at 110-400°C during the sintering process. ℃ discharge; the hydroxyl group contained in the an...

Abstract

The invention provides a method for appraising the genuine hydroxyl in ancient ceramics. Wherein, a laser Raman microprobe is used to check the genuine of ancient ceramics of more than 50 years old by detecting hydroxyl, namely, -OH in the glass phase in the glaze surface of the ceramic. The invention is studied by years of tests and verified by experimental units. Comparison tests are conducted on some ceramic pieces sintered 50 years before and ceramic pieces sintered in modern time as well as simulated ancient ceramic pieces, the test results show that any ceramic containing hydroxyl in the glass phase in the ceramic glaze surface is ancient ceramic sintered 50 years before; and any ceramic containing no hydroxyl in the glass phase in the ceramic glaze surface is sintered at modern time, is false ancient ceramic. Comparing with prior way for appraising ancient ceramic, the invention is scientific, practical, of accurate appraisal results, can be popularized in the genuine appraisal of ancient ceramics.

Description

technical field [0001] The invention belongs to the technical field of identification of ancient ceramics, and in particular relates to identifying the authenticity of ancient ceramics by using a laser Raman probe to detect the content of hydroxyl groups in ceramic glazes. Background technique [0002] my country has a long history of more than 2,000 years, and there are many precious unearthed cultural relics. Correct identification of ancient cultural relics is of great significance for understanding the ancient economy, politics and culture of our country. Cultural relics include national collections, local collections, and private collections. Some cultural relics are allowed to circulate in the market. At present, the cultural relics market is very chaotic, there are many fake cultural relics, the authenticity is unclear, and it is difficult to identify, especially for some precious cultural relics, the price is very expensive, some are worth tens of millions of yuan, a...
