The limestone is soft when quarried and therefore is easily worked, but case-hardens on exposure. Because of the purity, it is unusually massive, and can be cut in blocks 5' wide by 13' high by 30' long or larger. This is unusual for limestone and is one of the reasons that Indiana limestone is especially valued.
