ABSTRACT
Indirect methods of evaluation of wetting properties of fine particles or porous materials require se- lection of a reference liquid, for which the contact angle is equal to zero. In our investigation, the cap- illary rise method and film flotation were used for: glass microglobules - water and glass microglob- ules – decane systems. The data for the reference liquid and the examined one are introduced into the modified Washburn equation and the contact angle is calculated.
