Abstract: A 4-in-1 antique identification method combines visual inspection, a colorimetric method, microscopic observation, and a density comparison method to form conclusions as to the date of an antique object. Among them the density comparison is to detect the identified object's unit weight, and compare it to known data of historical unit weights of objects, to determine the age of the object being measured. This combines the antique's inherent physical constant to confirm its age. This is repeated for each step, to provide a number of estimated age results for the object. If the results are in agreement, the result can be considered reliable and the object can be deemed authentic. This method especially applies to the identification of porcelain, jade and bronze with less equipment and easier operation.

Abstract: The present invention makes Yi's 4-in-1 antique identification method known to the public. It combines visual inspection, colorimetric method, microscopic observation and density comparison to one method. Among them the density comparison is to detect the object's unit weight, contrast the unit weight of object to determine the age. This invention combines the antique's inherent physical constant to confirm its age. The present invention may be used for the identification of porcelain, jade and bronze. The user then obtains more accurate results by using this easy, simple and cost-effective method.
