About the use of Nautical Foundry Molds:
This wooden pattern was used in the process of sand casting. Molding material, such as sand, would be packed around this pattern inside of a casting flask. The sand is then compressed in a process known as ramming. When the molding material reaches the proper density, the pattern is removed. Molten metal is then poured into the cavity created by the positive mold. Once the metal has cooled and hardened, the sand is then broken away and the metal casting is removed. This pattern was used to cast a part of a ship or nautical component.
