Ceramic moulds in the investment casting technology are made by depositing on the wax pattern subsequent layers of a liquid ceramic mass together with a granular matrix. A quality of castings depends on building of individual layers. The results of the ceramic moulds permeability obtained by means of the newly developed measuring method are presented in the hereby paper. Due to the applied solution it is possible to perform measurements also for the first layers which have the decisive influence on a permeability of the whole multilayer ceramic mould. Investigations of the influence of the matrix grain size and annealing temperature on the permeability of ceramic moulds were carried out.
