Carving in stone is a process that has been used for centuries to create sculptures, monuments, and other works of art. Etching, sculpting, and chiseling are all techniques used to carve in stone. Etching involves using a sharp tool to cut into the surface of the stone, creating a design or pattern. Sculpting involves shaping the stone into a desired form, while chiseling involves using a hammer and CHISEL to shape the stone into a desired shape. All three techniques can be used to create intricate designs and works of art that are meant to last for generations.
