grinding stone analysis

Ancient starch analysis of grinding stones from

2019-2-1  In this study, we present the results of a residue analysis of grinding and pounding stones from the arid zone in South Australia. The aim of this study was to investigate the survival of potentially use-related residues, specifically starch, phytoliths and collagen, the last being a likely indicator of multifunctional use.

Aurignacian grinding stone from Surein I (Crimea):

The analysis of the grinding stone involved a methodological refinement which includes the use of different resolution microscopes such as stereomicroscope, reflected and transmitted light (IHMC, RAS), digital microscopy (hereon DM) and electron scanning microscope, SEM, covering wear-traces and U-RBR, namely starch grains.

Functional analysis of stone grinding and polishing

These include (1) grinding cereals, (2) pounding temper, colourants and various plants, (3) shaping mineral, vegetal and animal objects by polishing (schist, limestones, bone, antler, wood), (4) softening skin. A significant observation concerns the use of small handstones for grain dehusking and larger handstones for grain grinding.

2017-2-1  The performed blind test is an exploratory test to evaluate the potential and reliability of wear and residue analysis to identify what a grinding stone was used for. It was not intended to evaluate the reliability of wear or residue analysis to distinguish between used and unused grinding stones, which will be the subject of subsequent tests.

Archaeologists define stone artifacts that are altered by or used to alter other items through abrasion, pecking, or polishing as “ground stone.”. This includes mortars and pestles, abraders, polishers stones, and hammerstones, and artifacts shaped by abrasion or pecking, such as axes, pipes, figurines, ornaments, and architectural pieces.
