Abstract

A method for manufacturing a casting mold having a laminated wall, consisting of a mass of refractory and granular bonding material, comprising the steps of applying to the model a first layer of a gellable suspension of a fine-grained refractory powder in a solution of a binder, in particular in a silica sol, by applying a refractory powder of coarser grain on the still wet layer, dry the first coating layer, obtaining at least one supporting layer by means of a gellable suspension of a refractory powder in a solution of a binder and drying the resulting mold, before or after removing the model, until said mold has sufficiently hardened, this method being characterized in that the first dry coating layer, to which the refractory powder is applied, It is moistened with a liquid that, when mixed with the liquid phase of the mixture used for the first supporting layer e, it provides a homogeneous liquid.
