ʻO ke one hoʻoheheʻe ceramic no ke kaʻina hana one ʻōmaʻomaʻo

Green Sand Castings are castings made using wet sand or “green sand” molds. The sand is not green in color nor do the molds use “greensand,” a greenish color sandstone. Instead of the sand is called “green” because it has moisture in it (like green wood) before the sand dries out when molten metal is poured in the mold.

What gives the sand moisture and helps the sand stick together when making molds is the clay that is mixed in the sand. Bentonite clay and the sand mixed together provide strong molds that can be created on an automated assembly line.
