Abstract
Quantitative determination of barium in Chinese porcelains from the seventeenth century to modern times together with some modern non-Chinese porcelains was made with the use of calibration curves obtained by the addition method. All Chinese porcelains from K'ang Hsi (Ka-ngxi, 1662-1722) up to World War II were found to have a barium content between 100 ppm and 130 ppm. For those made after World War II, the barium content varies from 60 ppm to 7000 ppm, and only a few pieces are in the range from 100 ppm to 130 ppm, making it possible to identify most of the modern fake reproductions.
