* Smooth and cool: This is typical for freshly broken or polished limestone. It can feel similar to marble, but often with a slightly rougher texture.
* Slightly rough: This is common in weathered limestone, where the surface has been exposed to rain, wind, and other elements. The surface can feel grainy, like sandpaper.
* Chalky: Some limestones, particularly those rich in calcium carbonate, can feel chalky and powdery. This is especially true if the rock is soft or porous.
* Hard and brittle: Some limestones can be very hard and dense, with a brittle feel. This is more common in crystalline limestones.
Ultimately, the texture of limestone will depend on the specific rock sample. It's best to touch and feel it yourself to get the best sense of its unique characteristics.
