Traditionally, circles have been perceived as symbols of wholeness, unity, and the eternal cycle of life. In many ancient cultures, circles were often used in ceremonial contexts, representing the infinite nature of existence. The act of casting a circle is both an artistic and spiritual endeavor, often performed within a group, although it can also be done alone.

At its core, sand casting involves creating a mold from sand, which is then filled with molten material to form a desired object. The mold consists of two halves, typically referred to as the cope (top half) and the drag (bottom half). The sand used in this process is mixed with binding agents to enhance its strength and stability, allowing it to retain the shape of the mold once the pattern is removed.
