How does the use of green sand molds affect the surface finish of cast iron figurative sculptures?

The use of green sand molds in casting iron figurative sculptures significantly impacts the surface finish, often resulting in a distinctive texture. Green sand, a mixture of sand, clay, and water, is cost-effective and reusable, but its porous nature can leave a slightly rough or grainy surface on the final sculpture. This texture may require additional finishing work, such as grinding or polishing, to achieve a smoother appearance. However, the organic, earthy quality of green sand molds can also enhance the artistic appeal of figurative sculptures, adding a rustic or vintage charm. For intricate designs, the mold's ability to capture fine details depends on the sand's grain size and compaction. While green sand molds may not produce the ultra-smooth finishes of other methods like investment casting, they remain popular for their versatility and affordability in artistic metalworking.
