石英的两个晶面之间的光接触获得了非常大的电荷，相对于aZcut， anXcut面是正的。这种效应不是压电的，因为当用X+代替X+时，它不会逆转。使用玻璃体二氧化硅获得的不可忽视的电荷可能是由于早期结晶的斑块。清洁良好的石英和二氧化硅表面粘附的趋势似乎不影响充电，并且粘附不是电的起源。静电力对摩擦力的贡献不大可能是可观的。
Very large charges are obtained from the light contact of two crystal faces of quartz with each other, anXcut face being positive with respect to aZcut. The effect is not piezoelectric in origin, since it does not reverse when anX_ face is used instead of an X+. The not inconsiderable charges obtained using vitreous silica may be due to patches of incipient crystallization. The tendency of well-cleaned quartz and silica surfaces to adhere seems not to affect the charging, and the adhesion is not electrical in origin. It is unlikely that electrostatic forces ever contribute appreciably to the force of friction.
