Foundry Manual - Part 2 - Maritime

A mold is made by shaping a suitable sand mixture around a pattern of the desired form. A metal or wood box (flask) is used to retain the sand. The pattern is then removed from the sand, leaving a cavity in the sand into which the molten metal can be poured. The molder's skill is the basic skill of the foundry.
