A method of casting non-ferrous metals having a melting point below that of ferrous metals comprising the steps of making a mould predominantly of zircon sand and a chemically hardenable organic resin binder which can be hardened at a temperature not exceeding 50 DEG C, casting molten non-ferrous metal into said mould to make a casting and separating the used sand from the casting. The mould and cores, if any, comprises, in addition to a catalyst or hardening agent for the resin binder; <IMAGE> |
