Translations:Mortar and pestle/4/en

A key advantage of the mortar is that it presents a deeper bowl for confining the material to be ground without the waste and spillage that occur with flat grinding stones. Another advantage is that the mortar can be made large enough for a person to stand upright and adjacent to it and use the combined strength of their upper body and the force of gravity for better stamping. Large mortars allow some individuals with several pestles to stamp the material faster and more efficiently. Working over a large mortar that a person can stand next to is physically easier and more ergonomic (by ensuring a better posture of the whole body) than for a small quern, where a person has to crouch and use the uncomfortable, repetitive motion of hand grinding by sliding.
