Goulac, also known as Glutrin, is a core binder developed from wood pulping. It is made from lignin pitch. The material has a dark colour and is soluble in water. Goulac water was used to make Gallagher sharp sand. It was trademarked in the 1940s. It prevents a chemical reaction between lead arsenate and lime sulphur. When used to make mold cores from sand, it results in a very hard surface after baking, however the sand can absorb moisture if the core is not used soon after being prepared. Use
