What is subtractive method for sculpture?

The subtractive method for sculpture involves creating a three-dimensional form by removing material from a solid block of substance, such as stone, wood, or metal. This technique typically begins with a rough shape, which is progressively refined by chiseling, carving, or sanding away excess material. The final piece emerges through careful subtraction, revealing the desired form and details. Historically, this method has been used by many renowned sculptors to create intricate and expressive works of art.
