What are the benefits of using oil mixed with sand for casting?
Different types of oil are used for different purposes when mixed with sand for casting.

Vegetable oil is used when casting plaster or concrete because it is a natural release agent that prevents the plaster or concrete from sticking to the mold. Petroleum products are used when casting wax because they have a low melting point and provide a smooth surface for the wax to cool on.
