Limestone is a harder grey rock which can form spectacular caves, some of which are open for the public to explore. Both these rocks are made of soluble calcium minerals, which formed millions of years ago from the skeletons of sea animals.

What is white limestone?

White limestone is highly valued for its luminosity and the homogeneity of its light tones. Some of them present specks of very tenuous colors that are also distributed uniformly at the surface. In other cases, they exhibit more extensive lines or drawings due to the morphology of the fossils they contain.

Does limestone break easily?

This rock has already a brittle structure, which causes break-ups and dissolves. Inherent weakness in the stone itself or the gradual breakdown of the binder used for building it and the external factors are the main reasons which affect the durability and strength of the limestone and which finally cause crumbling.
