  • examples of grinding method related to chemistry

    This grinding method could have been inherited from the earlier hunter-gatherers, but could also result from a broad-spectrum subsistence strategy adopted at Jiahu. By comparing the properties and ethnographic uses of different plant species, it is also suggested that cereals such as rice were a more sensible choice for the dry-grinding process.
