Stone Grinding laucke.au

Early methods of stone grinding involved the simple practice of crushing grain between two stones, roughly grinding it to form a ‘meal’. The Romans refined this process by utilising the quern, an arrangement of two millstones with the upper one being turned by muscle power either of a slave or an animal such as an ox.
