The paper presents the results of the absorption effectiveness measured for electromagnetic waves with a frequency of 2.45 GHz penetrating selected quartz mold and core sands matrixes. Research was conducted with a usage of the unique microwave slot line for assessing, on the basis of the measured parameters of looseness, the effectiveness of microwaves absorbing capacity by the matrixes of molding sands. Examinations were focused on the high-silica quartz matrixes from various mines with a different grain size composition and humidity. Usage of the unique measuring device, designed especially for this type of research, has made possibility to systematize knowledge of the dynamics and efficiency of microwaves absorption while penetrating humid matrix of molding sands. Analysis of the study results indicate, that the process of microwaves absorbing is affect, in addition to water located on the matrix grains surfaces, by the grain size distribution and the origin of the quartz sand.
