CAST, among founders, is applied to tubes of wax fitted in divers parts of a mould of the same matter, by means of which, when the wax of the mould is removed, the melted metal is conveyed into all the parts which the wax before possessed.
CAST also denotes a cylindrical piece of brass or copper, slit in two, lengthwise, used by the founders in sand, to form a canal or conduit in their moulds, whereby the metal may be conveyed to the different pieces intended to be cast.
