Method of forming a sand core for metal melting, characterized in that it comprises placing in contact with a defining surface of the foundry, a mixture of a finely divided refractory material, from about 0.5 to 10%, based on the weight of said refractory material, of a liquid binder composition consisting essentially of an aqueous solution of alkali metal silicate with an alkalinity of the order of 18 to 30, and of about 3 to 100%, based on the weight of said liquid binder, a sink capacity communicating agent, consisting essentially of Al2O3, and the further drying of the mixture.
