Sandstone

Sandstone is a type of common industrial natural stone. It has the lowest tensile strength and the highest thermal conductivity among natural stone materials. The graph bars on the material properties cards below compare sandstone to other natural stone materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
