FIELD: foundry.
SUBSTANCE: apparatus for making casting ceramic molds includes electrolyzer connected with negative terminal of electric current source; three vessels communicated with electrolyzer though valves. Two of said vessels are filled with suspension. At changing chemical content of suspension in electrolyzer pumps are operated for pumping suspension from electrolyzer to empty vessel and for pumping suspension from second vessel to electrolyzer in order to make up chemical content of suspension in electrolyzer and to provide desired content of suspension.
EFFECT: possibility for producing casting molds with similar chemical content and with similar mechanical properties.
