Translations:Mortar and pestle/8/en

Mortars and pestles were invented in the Stone Age when humans found that processing food and various other materials by grinding and crushing into smaller particles allowed for improved use and various advantages. Hard grains could be cooked and digested more easily if ground first, grinding potsherds into grog would vastly improve fired clay, and larger objects such as blocks of salt would be much easier to handle and use. Various stone mortars and pestles have been found, while wooden or clay ones would perish much more easily over time.
