Sandstone can also be processed into Sand. Processing Gravel has a 15% chance to yield Flint as a secondary product, and processing Sandstone has a 40% chance to produce Niter. Netherrack is ground into Gravel, but is a good way to obtain Sulfur at a 15% chance. A large amount of other items can be pulverized.

natural density of red-sandstone specimen is 2.09~2.16 g/ cm3. The optimal water content and maximum dry density of the red-sandstone specimen after weathering and disinte-gration are 10.62% and 2.052 g/cm3, respectively. The aver-age unconfined compressive strength (UCS) of the red-sandstone specimen in natural conditions is 13.8 MPa.
