Grindstone
A grindstone, also known as grinding stone, is a sharpening stone used for grinding or sharpening ferrous tools, used since ancient times. Tools are sharpened by the stone's abrasive qualities that remove material from the tool through friction in order to create a fine edge. Similar to sandpaper, each stone has a different grit that will result in sharper or duller tools. In Australia, Aboriginal peoplesAbstract The functional study of ground stone artefacts and the analysis of charred plant remains together demonstrate that plant foods played a significant role in Holocene grinding stones at Madjedbebe reveal the processing of

Food or fibercraft? Grinding stones and Aboriginal use of
Here we consider ethnohistorical evidence for stones in fibercraft and the processing of Triodia grass (spinifex) as a case study. We compare functional traces on experimental stones with traces on a museum specimen (CMAA 1926.591), which was collected ethnohistorically and reportedly used for ‘grinding spinifex leaves’.Archaeological sites with surface hearths are a ubiquitous feature across the arid zones of the Arabian interior. At Jebel Oraf, in the Jubbah basin of the Nefud Desert of northern Arabia, numerous grinding stone fragments were found in association with hearths, though the original purpose of these stones was unclear owing to the poor Plant, pigment, and bone processing in the Neolithic of northern

Grinding-stone implements in the eastern African
Grinding-stones in the PN. Grinding-slabs have been recovered from a number of Pastoral Neolithic sites across East Africa such as Narosura, the Nakuru Burial Site, Crescent Island (Main), Njoro River Cave, Keringet Apart from plant food processing, one of the grinding tools was also involved in processing bone. For instance, the sites of Tanghu and Jiahu show similarities in terms of their stone tool (e.g. grinding slabs with feet, stone sickles, and axes) and pottery assemblages (e.g. cooking vessels).Full article: Plant Foods and Different Uses of Grinding Tools at

Grinding grounds: Function and distribution of grinding stones
However, microscopic residues from five grinding stones indicate both animal (collagen and bone) and plant (cellulose, starch, phytoliths) processing. Specific plant taxa indicated by the residue study are: Chloridoid and Panicoid grasses (including Triodia spinifex), Acacia,Marsilea nardoo and tubers (most likely Ipomoea costata, Since the introduction of diesel-powered grinding mills (posho mills) in the 1980s, the use of grinding-stone tools for processing plant materials has declined in Marakwet. However, distance and monetary constraints render diesel mills less accessible for many, so grinding-stones remain important processing tools.Back to the Grindstone?

Functional Studies of Prehistoric Grindingstones OpenEdition
Grindstones differ from other stone tools because they represent, to use Leroi-Gourhan's terms, a specific mode of action on material, aimed at crushing, pulverizing, grinding, or more generally reducing into particles or powder. This category of tools basically covers lower grindingstones, handstones, pestles and mortars. I will use this definition rather processing activities. Early stone grinding tools are known from the lowest Upper Paleolithic layer at Qafzeh Cave, including a shallow mortar with traces of ochre staining on the rim.10The Archaeology of the Daily Grind: Ground Stone Tools and Food
