Abstract

Oils for making foundry cores consist of either (1) a mixture of stearin or other fat pitch with oils that are derived from coal tar, brown coal tar, or wood tar and boil between about 220 and 400 DEG C.; or (2) the same tar oils oxidized to semi-fluid or resinuous products, and mixed or not with stearin pitch, fat pitch, or other pitch, or with other oxidized oils, such as oxidized linseed, maize, fish, or other fatty oil. Resins, resin oils, or resin-like substances, and molasses or other emulsifying agents may be added. In an example 3-5 lb. of tar oil, 2 lb. of stearin pitch, and 1-2 lb. of coumaron resin are mixed together. The use of linseed oil alone, or of a mixture of mineral oil and fat pitch is referred to.
