Abstract

Method of procuring refractory molds for metallic castings from a crushed refractory material and a binder produced "insitu" by mixing said refractory material with a lower alkyl silicate as defined herein inwardly and an aqueous acidic gelling agent whose method comprises the operation of igniting the alcohol formed by hydrolysis of the binder and escaping from all surfaces of the mold as soon as the latter has hardened by gelation, the mold being sustained during the combustión of said alcohol from all surfaces of the mold so that the ignition and alcohol combustión is carried out equally from all surfaces.
