Effects of physical and chemical properties on whiteness of cigarette ash have been studied. The whiteness of cigarette ash could be measured successively with a Photovolt Photoelectric Reflection Meter. In cigarettes made from Bright leaves, the reflectance has close relationships with weight per cigarette and the smoking conditions such as puff volume and frequency of puff; on the contrary, in cigarettes made from Burley or Japanese Native leaves, the reflectance is almost constant under any weight per a cigarette and any smoking conditions. The whiteness of cigarette ash of various tobacco leaves decreases in the following order: Bright (and Turkish), Japanese Native “Matsukawa-ha”, Burley, and Japanese Native “Daruma-ha”- Both the kinds and amounts of each inorganic constituent contained in the leaves vary the whiteness of cigarette ash.
