Mixing Moulding

This document provides instructions for mixing molding sand (greensand) for foundry casting. It describes sifting various types of sand and clay to remove large particles. It recommends using fine silica sand for the best surface detail. It details weighing and mixing the sanded components with a small percentage of clay and water until the mixture holds its shape when squeezed but does not stick to hands, indicating it is the right consistency for mold making. After mixing and resting, the final mixture is tested and determined to be good molding sand.
