Compressed Cobblestone (Extra Utilities 2)

Compressed Cobblestone is a storage block added by Extra Utilities 2. It may be used to reduce the space occupied by cobblestone. Compressed Cobblestone may also be compressed to form Double Compressed Cobblestone, which may be, in turn, compressed into Triple Compressed Cobblestone. This process may be repeated until Octuple Compressed Cobblestone is formed, at which point further compression is not possible.
