Lost-wax casting

Definition

Lost-wax casting is a metalworking process used to create intricate metal objects by forming a wax model that is encased in a mold. Once the mold is made, the wax is melted away, leaving a hollow cavity into which molten metal is poured. This method allows for detailed and complex shapes to be produced, making it particularly significant in the production of tools and decorative items.

5 Must Know Facts For Your Next Test

1. Lost-wax casting allows for highly detailed and ornate designs, making it ideal for both functional tools and decorative artifacts.
2. The process involves creating a wax model that is then coated in a heat-resistant material to form the mold before the wax is removed by heating.
3. This technique was widely used during the Viking Age to produce tools, weapons, and jewelry, reflecting the artisans' skill in metalworking.
4. After the wax is melted away, the mold can be reused for multiple castings, providing an efficient means of production.
5. Artifacts created using lost-wax casting have been found at archaeological sites, providing insights into the technological advancements of past cultures.
