Sand is mixed with clay (binder) and water. The sand must be permeable (allows gas to escape) and cohesive (holds its shape). You ram the sand around the pattern, remove the pattern, and cut the sprue and riser holes.
Uses a wax pattern coated in ceramic; known for high precision. Aerospace components, jewelry. Lost-Foam Casting
