Abstract
A method of manufacturing a foundry mold or core comprising forming a fluid mixture which is stable against breakage before curing and which comprises a foundry sand and a foamed aqueous phase comprising resin condensate, foaming agent and a acid curing agent, pour the fluid mixture into a box of molds or cores and let the mixture harden, and in which method the total amount of water in the fluid mixture is 0.9 to 1.5% and the condensate from resin is free of urea and is a condensate of two or more of phenol, furfuryl alcohol and formaldehyde.
