Beer
Owing to the hardening influence of the gluten, starch, albumen, etc., contained in beer, the bottoms of barrels, and sometimes the beer itself, was formerly used extensively for hardening the surface of cores and moulds, being sprinkled thereon before they were placed in the oven to dry. It has, however, been to a great extent superseded by molasses-water, glue-water, and the very numerous patented core-washes which may now be obtained from the foundry-supply dealers. See CORE-SAND; COREWASH; MOLASSES; GLUE.
