A new method for measuring moisture in pottery materials using a thermal neutron transmission gauge is reported. The moisture response of the white mud from Yixing Jiangsu has been calculated theoretically. The Yixing white mud from Jiangsu
the Jiepai Maji mud from Hunan
and the Zimujie soil from Shanxi are calibrated experimentally. The calibration curves all follow a linear law of In (1/T) against m. The precision of the moisture measurement is ±0.40wt%
