抄録	Whiteness in colour of talc is one of the most useful property in commercial uses, and it is used in ceramics and as a filler in paint, paper, and rubber. The present writer has carried out some quantitative studies on the whiteness as one of physical properties with the automatic photo-electric spectrometer. Consequently, whiteness value being calculated by the Hunter equation amounts to 88.9% for the maximum. In general, however, the talc contains the other minerals as impurities, therefore the whiteness in colour of talc decreases from 88.9% to 72.3% with the increase of impurities.
