Limestone | Characteristics, Formation, Texture, Uses, & Facts

Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation …

A Look Into Carving Limestone

Limestone originates in the ocean, and is composed mostly of calcium carbonate. Calcium carbonate appears chalky and powdery, and gives limestone its malleable qualities. Because limestone is such a soft yet durable stone, it's ideal for carving! The Carving Process. Limestone is soft enough that it's relatively easy to carve.
