The molding sand becomes incorporated into the casting metal and decreases the ductility, fatigue strength, and fracture toughness of the casting.

A related source of defects are drops, in which part of the molding sand from the cope drops into the casting while it is still a liquid.

Two types of molding sand are natural bonded (bank sand) and synthetic (lake sand); the latter is generally preferred due to its more consistent composition.
