FIELD: foundry. SUBSTANCE: method comprises steps of heating mold with pattern until melting outer layer of pattern composition; preliminarily according to condition ν≤106•σ•K, received experimentally and by calculation determining viscosity ν of pattern composition; determining strength value σ and penetrability K by testing samples of ceramic molds. If above mentioned condition is satisfied, specific capacity of ceramic mold is more or equal to specific volume of filtered pattern composition. Mold resistance against pressure of pattern composition prevents cracking and rupture of mold. EFFECT: enhanced efficiency of method. 1 tbl
