Historical information

Grindstones like this were not carried but hidden in special places with subtle indicators known only to the same tribe or nation. The small and deep nature of the pits suggests this rock may have been used for ochre with the smaller pits being used for water or fat to mix with the pigments. The very hard and dense nature of the rock means materials would not be contaminated during the grinding process.


This rock is likely to be very old and is potentially significant from ceremonial perspective. Stones like this have been known to be passed on through multiple generations and been in use for hundreds and possibly thousands of years.

Physical description

This grindstone has hollows on both sides. One large hollow on one side measures approximately 7 cm across and 2 cm deep. The opposite side is distinguished by 3 pits, one large (5 cm wide by 3 cm deep) and two small indentations 2cm by 1cm. The hollows have been chipped and smoothed. The base rock is in the shape of a flattened and slightly elongated sphere, it appears to have been water worn.

Inscriptions & markings

The side with three pits also bears recent scratches believed to be cut by a disk plough. It also appears to have a capital "W" inscribed in the largest pit.
