Century Dictionary and Cyclopedia
    • n levigation The act or operation of grinding or rubbing a solid substance to a fine impalpable powder. A mortar and pestle are commonly used in the process, and it is completed by allowing the coarser particles to settle in water, then decanting the latter, letting it stand till the fine powder has fallen to the bottom, and finally pouring off the water. In the chemical analysis of minerals this process is repeated until the mineral has been reduced to a sufficient degree of fineness, the coarser part being subjected to further pulverization after each separation by the aid of the water.
