Abstract: A process is described for the preparation of free-flowing, readily meterable and pressable glaze compositions for the dry-pressing of glazed ceramic products. The process is inexpensive to carry out and gives edge-stable pressings. To this end, a binder, in particular polyvinyl alcohol, is added to the glaze powder, which is pelletised to a particle size of from 0.05 to 3 mm, and mixed with 0.1 to 5 % by weight of a highly dispersed, hydrophobised oxide, in particular silicic acid (silica), and the mixture is mixed for from 5 to 60 seconds.
