Core-compound
A substitute offered by various patentees for flour, resin, molasses, sawdust, or other substances commonly employed for stiffening, hardening, and venting cores. It is claimed for most of these compounds that they give body to the sand, burn without smoke or smell, are always uniform and ready for use; that they do not blow, they rap out easily; and, last but not least, that they are cheaper than any of the several things mentioned above. There certainly is one advantage in these prepared compounds: once the exact quantity for effective use is ascertained, the too common annoyance of too much or too little flour, etc., is obviated to the sensible advantage of all concerned. See FLOUR; ROSIN; MOLASSES; VENTING.
